fstab, unusual behavior of "missing UUID"
by Joseph Hesse 06 Jul '13

06 Jul '13

I have the following as the last line of my /etc/fstab file on a computer running CentOS6.4.. UUID=3b550884-8d05-41a5-a205-17b6d7269dd1 /mnt ext3 rw,suid,dev,exec,noauto,nouser,async 0 2 The UUID refers to an ext3 partition of a removable USB drive. If the USB drive is not plugged into the computer the computer will not boot. It seems that this is the incorrect behavior since "noauto" means there is nothing to mount. I noticed this situation since an almost identical /etc/fstab on a Fedora 18 computer will boot without the USB drive being plugged in. The reason this is important to me is that I want to plug my USB drive into a running computer and then mount it with "# mount /mnt" so I can do backups. Thank you, Joe Hesse

Windows 2008 R2 on KVM
by linuxsupport 06 Jul '13

06 Jul '13

Hi All, I have a KVM machine with CentOS 6.4 (64bit), I have a Linux guest running well on this, I created a Windows 2008 R2 guest and once I start it, after sometime all the host memory get exhausted and both the guests (linux+win) killed. Host has 32 GB RAM, 8 GB is allocated to Linux guest and 8 GB to Windows. Any idea? anyone experienced similar issue?

postfix + amavisd-new
by Timothy Murphy 06 Jul '13

06 Jul '13

I've been following the instrunctions in <http://wiki.centos.org/HowTos/Amavisd> for installing Amavisd, Clamav and SpamAssassin on top of postfix/dovecot . Dovecot is working fine, but I want to deal with spam email. (I am using sendmail/dovecot with procmail and spamassassin on another server, but decided to go over to postfix on this server when I saw it is now the CentOS default.) However, I came to a problem at the end of the instructions, when I appended ---------------------- # ========================================================================== # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) # ========================================================================== amavisfeed unix - - n - 2 lmtp -o lmtp_data_done_timeout=1200 -o lmtp_send_xforward_command=yes -o disable_dns_lookups=yes -o max_use=20 ---------------------- to /etc/postfix/main.cf . After doing this, when I ran #postfix reload or "sudo service postfix restart" I got the error message ---------------------- postfix: fatal: /etc/postfix/main.cf, line 699: missing '=' after attribute name: "amavisfeed unix - - n - 2 lmtp -o lmtp_data_done_timeout=1200 -o lmtp_send_xforward_command=yes -o disable_dns_lookups=yes -o max_use=20" [all one line] ---------------------- Any elucidation or advice gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

odd inconsistency with nfs
by Miranda Hawarden-Ogata 05 Jul '13

05 Jul '13

I'm having an interesting/odd problem with nfs (I think). We recently (Monday/Tuesday) upgraded our file server from an ancient redhat 7.3 system to a shiny new centos 6.4 system. We don't see any issues between the other centos boxes, but things get a bit weird when we start mounting on the old solaris clients. The initial symptom was that the 'tab complete' wasn't working, and then we noticed that typing 'ls *' in the mounted directory was bombing. I tried forcing the mounting back to nfs3 but it's not consistent. I've set up two boxes as servers and one of the solaris boxes is my client. Each server has two shares that are mounted on the client. Of those four, one of them works properly and the other three do not. I've spent most of the day trying to debug this and I cannot for the life of me tell why one share works and the rest don't. Nothing seems to be special about that share versus the rest. Here are notes on how things are set up. on duke: (nis server) vi /etc/ypfiles/automap scrs1_bolt -soft,intr,retrans=1 boltzmann:/scrs1_bolt summit_bolt -soft,intr,retrans=1 boltzmann:/summit_bolt scrs1.mirror -soft,intr,retrans=1 goblin:/scrs1.mirror summit.mirror -soft,intr,retrans=1 goblin:/summit.mirror ( cd /var/yp ; make ) on boltzmann: (nfs server) df -h Filesystem Size Used Avail Use% Mounted on /dev/sdb2 50G 13G 37G 26% / tmpfs 3.9G 1.2M 3.9G 1% /dev/shm /dev/sdb3 177G 188M 175G 1% /aux /dev/sda3 208G 44G 164G 21% /aux2 mkdir /aux/scrs1_bolt mkdir /aux2/summit_bolt ln -s /aux/scrs1_bolt /scrs1_bolt ln -s /aux2/summit_bolt /summit_bolt chmod 777 /aux/scrs1_bolt /aux2/summit_bolt service nfs restart vi /etc/exports /scrs1_bolt xxx.xxx.xxx.0/24(rw,no_root_squash,sync,insecure) /summit_bolt xxx.xxx.xxx.0/24(rw,no_root_squash,sync,insecure) exportfs -rv on bigdog: (client) mkdir /tmp/test/b1 /tmp/test/b2 /tmp/test/g1 /tmp/test/g2 touch /tmp/test/b1/nothing_is_mounted /tmp/test/b2/nothing_is_mounted /tmp/test/g1/nothing_is_mounted /tmp/test/g2/nothing_is_mounted mount -F nfs -o nfsvers=3 boltzmann:/summit_bolt /tmp/test/b1 mount -F nfs -o nfsvers=3 boltzmann:/scrs1_bolt /tmp/test/b2 mount -F nfs -o nfsvers=3 goblin:/summit.mirror /tmp/test/g1 mount -F nfs -o nfsvers=3 goblin:/scrs1.mirror /tmp/test/g2 ls -l /tmp/test/* -rw-r--r-- 1 root other 0 Jul 3 14:39 /tmp/test/nothing_is_mounted /tmp/test/b1: total 24 -rw-r--r-- 1 root other 0 Jul 3 12:32 SUMMIT_BOLT -rw-r--r-- 1 root other 0 Jul 3 09:26 boltzmann_test_summit /tmp/test/b2: total 32 -rw-r--r-- 1 root other 0 Jul 3 12:31 SCRS1_BOLT -rw-r--r-- 1 root other 0 Jul 3 09:26 boltzmann_test_scrs1 /tmp/test/g1: total 280 -rw-r--r-- 1 root other 0 Jul 3 15:40 .00_summit_nas_volume -rw-rw-r-- 1 root other 0 Jul 3 15:03 SUMMIT_MIRROR /tmp/test/g2: total 120 -rw-r--r-- 1 root other 0 Jul 3 15:40 .00_scrs1_nas_volume -rw-rw-r-- 1 root other 0 Jul 3 15:02 SCRS1_MIRROR ls -la /tmp/test/b1/* -rw-r--r-- 1 root other 0 Jul 3 12:32 /tmp/test/b1/SUMMIT_BOLT -rw-r--r-- 1 root other 0 Jul 3 09:26 /tmp/test/b1/boltzmann_test_summit ls -l /tmp/test/b2/* ls: No match. ls -l /tmp/test/g1/* ls: No match. ls -l /tmp/test/g2/* ls: No match. mount /tmp/test/b1 on boltzmann:/summit_bolt read/write/remote on Wed Jul 3 15:41:11 2013 /tmp/test/b2 on boltzmann:/scrs1_bolt read/write/remote on Wed Jul 3 15:41:11 2013 /tmp/test/g1 on goblin:/summit.mirror read/write/remote on Wed Jul 3 15:41:11 2013 /tmp/test/g2 on goblin:/scrs1.mirror read/write/remote on Wed Jul 3 15:41:11 2013 umount -a /tmp/test/b1 /tmp/test/b2 /tmp/test/g1 /tmp/test/g2 If I use automount to access the shares on the client, the mounts are made by default with nfs4 and we see this same 'no match' behaviour. It's probably something really stupid but I'm just not seeing it... If anyone has ideas and/or needs more info, please let me know. -- Thanks! Miranda

gspca - running out of ideas
by m.roth＠5-cent.us 05 Jul '13

05 Jul '13

For video capture from a USB camera, as near as I can tell, there's a problem with the driver gspca_zc3xx with the latest update to the kernel. All our cameras were working fine before the update to 2.6.32-358.11.1; since, two cameras, both on fairly new Dell servers are screwed. Meanwhile, on some older servers, same update, no problems. Of the two bad ones, one's got AMD, and the other Intel Xeons. Without any changes to the configuration file, I get about 10% to 15% at the top ok, and everything below it is green. Googling, I find other folks have had green screens over the years, so it's not just some color setting on my workstation. By adding /usr/lib64/libvdpau.so.1 to the LD_PRELOAD in /etc/init.d/motion, I get the rest of the screen on the Intel box looking like it works, but there's a slight yellowish tinge to the rest of the screen, and when I watched what we see using mplayer tv:// -tv driver=v4l2:device=/dev/video0 not only do I see the same, but we had someone walk in view of the camera... and *only* that top little bit shows the motion; the other 80% or 85% shows only what's there, and *not* the rest of the person. I'd gone through doing an insmod ...gspca_zc3xx with force_sensor option, and the only one that works is the same one it chooses itself if I just do a modprobe. Anyone have any ideas? I *really* can't reboot either of these servers so as to bring them up with the previous kernel, since they're important. mark

sda and sdb reverse order with an external USB drive
by Joseph Hesse 04 Jul '13

04 Jul '13

Hello I am using 64 bit CentOS 6.4 on an i7 laptop with one sata drive and a CD drive. I installed CentOS by manually partitioning sda as: sda1 as /boot, sda2 as swap, sda3 as /. The booted system works great. When I insert an external USB drive, formatted as ext3, the hard drive on the laptop and the USB drive are either sda or sdb, depending upon the order on which I insert the USB drive and boot the system. Please see the two mount commands below for each of these situations. This seems to work in either order except for the fact that I don't want my USB drive to automount. What I want is that after I insert the USB drive in a running system and wait 15 seconds, I want to mount the USB drive with the command "# mount /mnt". To accomplish this I added a line to /etc/fstab but it didn't work. When I uncomment the last line in fstab (see below) the computer hangs and doesn't boot. I was successful with this strategy on a similar laptop with Fedora 18 but not my current one. Thank you, Joe Hesse ======================================================================================== The following mount command was issued by first completely booting CentOS and then inserting the external USB Drive. Note the sda3 is / and sda1 is /boot. [root@XoticPC ~]# mount /dev/sda3 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/sda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) /dev/sdb1 on /media/GoFlex type ext3 (rw,nosuid,nodev,uhelper=udisks) ======================================================================================== The following mount command was issued by inserting the external USB drive in a powered down computer and then booting. Note the sdb3 is / and sdb1 is /boot. [root@XoticPC ~]# mount /dev/sdb3 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/sdb1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) /dev/sda1 on /media/GoFlex type ext3 (rw,nosuid,nodev,uhelper=udisks) ======================================================================================== The /etc/fstab file was generated by the install process. The commented line at the bottom was added by me in an unsuccessful attempt to be able to insert the USB drive in a booted computer, not having it mount, and then control the mounting with "# mount /mnt". The last UUID is the UUID of sdb1 determined with the command "# blkid /dev/sdb1". # /etc/fstab UUID=1d7606b7-46b8-4b29-9a4e-a50a1f6a1759 / ext4 defaults 1 1 UUID=e0fdfeb1-e7a7-4a06-b5fa-7730c3c2e60d /boot ext4 defaults 1 2 UUID=d0e3c2ee-7c66-4d13-b387-1da958020b1a swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 #UUID=3b550884-8d05-41a5-a205-17b6d7269dd1 /mnt ext3 rw,suid,dev,exec,noauto,nouser,async 0 2

Java/Solr - Could not reserve enough space for object heap.
by Rafał Radecki 04 Jul '13

04 Jul '13

Hi All. # cat /etc/redhat-release CentOS release 6.2 (Final) # uname -r 2.6.32-220.17.1.el6.centos.plus.x86_64 # rpm -qa | grep solr apache-solr-3.5.0-1.5... I have a solr installation which is invoked: /usr/bin/java -Xms25g -Xmx25g -DSTOP.PORT=8079 -DSTOP.KEY=mustard -Dsolr.solr.home=multicore -jar start.jar After start/when the java process is running: # free -m total used free shared buffers cached Mem: 32093 23975 8118 0 189 5736 -/+ buffers/cache: 18049 14043 Swap: 4095 22 4073 So the machine has 32GB of RAM, and java process needs 25GB to start. When I make a restart the java process dies and in log: Jul 4 08:17:27 test.local solr: Error occurred during initialization of VM Jul 4 08:17:27 test.local solr: Could not reserve enough space for object heap Jul 4 08:17:27 test.local solr: [FAILED] Then a second restart is ok, the process starts and solr is responding. Have you had such problems? As I think during stop jvm gives back the memory to the operating system and then during start is requesting 25GB (can there be a lag in this process?). No other services are running on this machine. Best regards, Rafal.
