*BAD*gran_size
by m.roth＠5-cent.us 13 Jun '13

13 Jun '13

CentOS 6.4, current, Dell PE R720. Had an issue today with a bus error, and googling only found two year old references to problems with non-Dell drives (we just added two WD Reds, and mdadm raided them). So, looking through dmesg and /var/log/messages, I ran into a *lot* of G gran_size: 128K chunk_size: 256K num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 512K num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 1M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 2M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 4M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 8M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 16M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 32M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 64M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 128M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 256M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 512M num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size: 1G num_reg: 10 lose cover RAM: 0G *BAD*gran_size: 128K chunk_size: 2G num_reg: 10 lose cover RAM: -1G Googling finds various threads, and a bug or two, and one person has an answer of setting this in the kernel line in grub. HOWEVER, the one person who gave that thread's O/P what to put never responded to *how* he chose those parms. Anyone here have any idea how to chose them? mark

Link for Logical Volume has incorrect SE Linux context
by Clint Dilks 13 Jun '13

13 Jun '13

Hi A few days ago we rebooted a server and found that one of the Logical Volumes would not mount at boot, but mounted cleanly manually. So I traced the problem to SE Linux. Specifically the context for /dev/mapper/VolGroup01-lv_ staff is wrong. s -lsahZ /dev/mapper/VolGroup01-* lrwxrwxrwx. root root system_u:object_r:quota_db_t:s0 /dev/mapper/VolGroup01-lv_staff -> ../dm-25 lrwxrwxrwx. root root system_u:object_r:device_t:s0 /dev/mapper/VolGroup01-lv_student -> ../dm-24 I have tried to correct this with the Logical Volume active and mounted using chcon -v --reference /dev/mapper/VolGroup01-lv_student /dev/mapper/VolGroup01-lv_staff and while this command completes the context is not changed. Can someone confirm or deny that making the Logical Volume inactive and then repeating the chcon should change the link to the correct context? Thanks for any insight you can offer.

CESA-2013:0898 & CEBA-2013:0902, centos 5.9 repodata not pushed?
by Denniston, Todd A CIV NAVSURFWARCENDIV Crane 12 Jun '13

12 Jun '13

Johnny (& other CentOS folks), Am I being fooled by some proxies between me and centos (and all the centos mirrors, which what I normally use), or has the repodata for CentOS 5.9 updates not been updated since 03-Jun-2013 12:08? I was under the impression that the repodata on the main centos servers was updated about the same time as any CentOS-announce message going out, unless I also see a message from one of the admins indicating an issue, so I am very confused. Thanks for the feedback. repodata[1] 03-Jun-2013 12:08 CESA-2013:0898 mesa email[3] Jun 3 22:45:12 UTC 2013, rpm[2] 03-Jun-2013 22:45 CEBA-2013:0902 gfs2-utils email[4] Jun 6 14:55:49 UTC 2013, rpm[2] 06-Jun-2013 14:55 [1] http://mirror.centos.org/centos/5.9/updates/i386/repodata/ [2] http://mirror.centos.org/centos/5.9/updates/i386/RPMS/?C=M;O=D [3] http://lists.centos.org/pipermail/centos-announce/2013-June/019773.html [4] http://lists.centos.org/pipermail/centos-announce/2013-June/019779.html Even when this disclaimer is not here: I am not a contracting officer.

Re: [CentOS] sieveshell fails to start on CentOS 6.0

Try specifying both --user and --authname as appropriate. sieveshell can be misleading in its error messages, and you may actually have an authentication error rather than a connection error there. You could run it under strace to make sure. Devin

Size limitations in .htaccess
by Max Pyziur 11 Jun '13

11 Jun '13

Greetings, It seems that I've hit a size limitation when adding unwanted IPs to a "Deny From" line. Is there any place where this is specified? Also, if I hit the max length on a "Deny From" line, can I add another "Deny From" line? (Running CentOS 6, and the following version of Apache: httpd-2.2.15-28.el6.centos.x86_64) Much thanks, Max Pyziur pyz(a)brama.com

KVM console?
by Les Mikesell 11 Jun '13

11 Jun '13

I finally got access to some machines with more resources than the free VMware ESXi license allows which pushed me into trying kvm instead. Seems capable enough for what I need and can even import and run the existing vmdk images I already have. But, I have some questions about accessing the virt-manager console remotely for initial configuration, etc.. Normally I use freenx for remote GUI access and it seems to work except that on the Windows guest I tried the cursor position never stays in sync. Are there better ways to get remote access to the GUI or centralize access to a group of KVM servers? Or do most people automate the VM setup to the point where they don't need console access until it is up on the network where you can connect directly to the guest? -- Les Mikesell lesmikesell(a)gmail.com

Question on detect serial ports
by Jerry Geis 11 Jun '13

11 Jun '13

I have a small based atom machine. There are four serial ports on the machine. dmesg | grep tty shows 0, 1, 2 and 3. 2 and 3 are on interrupt 10 -and they worked. going into the BIOS COM ports 0 and 1 are also on IRQ 10 and not the standard 3,4. BIOS cannot set anything but IRQ 10, 11 for serial ports. Odd... So COM 0 and 1 dont work right away... I had to put this in the boot script. setserial /dev/ttyS1 irq 10 port 0x2e8 setserial /dev/ttyS0 irq 10 port 0x3e8 now they seem to work. I have no idea why the bios will not have IRQ 3 and 4 for com ports but I was surprised linux did not inquire from the bios and use it. Should it get that from the BIOS - or - just leave the manual setting and move on... jerry

XFS zero length file problem
by John R Pierce 10 Jun '13

10 Jun '13

we're running into a scenario similar to this with CentOS 6, zero length files after a system crash. http://oss.sgi.com/archives/xfs/2012-02/msg00607.html I'm not exactly sure which kernel version they are running in production (its in China), but I'm trying to find out. its probably a year or so old, our manufacturing operations folks do NOT like installing random updates without very good reasons. meanwhile, I wonder if anyone familiar with it knows if the fix that Dave Chinner discusses in that posting I link above has been backported to a recent EL6 kernel. -- john r pierce 37N 122W somewhere on the middle of the left coast
