XFS : Taking the plunge
by Steve Brooks 21 Jan '14

21 Jan '14

Hi All, I have been trying out XFS given it is going to be the file system of choice from upstream in el7. Starting with an Adaptec ASR71605 populated with sixteen 4TB WD enterprise hard drives. The version of OS is 6.4 x86_64 and has 64G of RAM. This next part was not well researched as I had a colleague bothering me late on Xmas Eve that he needed 14 TB immediately to move data to from an HPC cluster. I built an XFS file system straight onto the (raid 6) logical device made up of all sixteen drives with. > mkfs.xfs -d su=512k,sw=14 /dev/sda where "512k" is the Stripe-unit size of the single logical device built on the raid controller. "14" is from the total number of drives minus two (raid 6 redundancy). Any comments on the above from XFS users would be helpful! I mounted the filesystem with the default options assuming they would be sensible but I now believe I should have specified the "inode64" mount option to avoid all the inodes will being stuck in the first TB. The filesystem however is at 87% and does not seem to have had any issues/problems. > df -h | grep raid /dev/sda 51T 45T 6.7T 87% /raidstor Another question is could I now safely remount with the "inode64" option or will this cause problems in the future? I read this below in the XFS FAQ but wondered if it have been fixed (backported?) into el6.4? ""Starting from kernel 2.6.35, you can try and then switch back. Older kernels have a bug leading to strange problems if you mount without inode64 again. For example, you can't access files & dirs that have been created with an inode >32bit anymore."" I also noted that "xfs_check" ran out of memory and so after some reading noted that it is reccommended to use "xfs_repair -n -vv" instead as it uses far less memory. One remark is so why is "xfs_check" there at all? I do have the option of moving the data elsewhere and rebuilding but this would cause some problems. Any advice much appreciated. Steve

Hi Dennis, Keith, Thanks for your pointers. I tried disabling C-states and and pcie-aspm options. No luck so far. My box has to be rebooted once in every 2-3 days.

You can try running the machine with the kernel option "pcie_aspm=off" and see if that helps and also try to disable C-States or Power Saving all together in the BIOS. More Details here: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux… http://lists.us.dell.com/pipermail/linux-poweredge/2011-June/044901.html I've experienced lock-ups in the past because of these issues. The network device hung because it tried to go into power saving mode using ASPM and it failed and whole servers locked-up after being idle for a while because of a bug in Intel Processors regarding the deeper power saving modes (C-States) although these are supposed to be fixed since 6.3. Hope this helps. Regards, Dennis

Apache Directory Level access control
by James B. Byrne 21 Jan '14

21 Jan '14

CentOS-6.5 httpd-2.2.15 (centos) I am trying to understand how directory access control works in Apache-2.2. Does a means exist to revoke access in a subdirectory if access has been granted in a higher one? We restrict access to the entire site via htdigest but some directories are need to be further restricted by the group a user is assigned to. I have this situation: <Directory /> AuthType Digest AuthName ca.harte-lyne AuthDigestDomain / AuthDigestProvider file AuthUserFile /etc/httpd/access.d/.htdigest AuthGroupFile /var/data/hll_dav/htgroup Require group staff AllowOverride None Order allow,deny allow from all Satisfy All Options Indexes MultiViews IndexOptions FancyIndexing AddDefaultCharset UTF-8 </Directory> <Directory /Private> Require group management </Directory> In this setup a member of group staff who is not a member of group management nonetheless can list and download files in /Private. I want to prevent this. Is this possible and if so then how is this done? -- *** E-Mail is NOT a SECURE channel *** James B.

Problem installing Centos 6.4/6.5 from USB stick seen as HDD by BIOS
by Emmanuel Noobadmin 21 Jan '14

21 Jan '14

I'm trying to install C6.5 on a USB stick (created using Fedora LiveUSB Creator). The problem is the machine using an Intel ITX board sets the USB stick as a HDD instead of a CDROM. During install, the DVD couldn't find the installer automatically and I must choose the HDD option for it to proceed to network/timezone/storage setup. After the storage partitioning, it will throw an error that it is unable to read package metadata. Although there is an option to edit the repo information, there isn't an option to specify a hard disk. Switching to console, attempts to mount /dev/sdb as /dev/cdrom or /mnt/sr0 met with failure because the USB drive is in use. Previously I used 6.4 and downloaded 6.5 thinking it might just be an issue with 6.4 but both failed at the same point. There doesn't appear to be anybody else who encounter the same problem on a quick google. Is this considered a bug with anaconda or is there some kind of workaround such as forcing the system to mount /dev/sdb as cdrom despite already being mounted/busy?

mail tools preferences?
by m.roth＠5-cent.us 21 Jan '14

21 Jan '14

We don't have enough arguments here.... <g> I see that thunderbird's deprecated for RHEL 7, and they recommend evolution. I've certainly had some annoyances in the last couple-three years with t-bird. So, what are people's preferred mail tools, other than t-bird (or maybe mutt or pine.... <g>)? mark

VMware restricting to 3GB RAM
by Hersh Parikh 21 Jan '14

21 Jan '14

Hi, I am running VMware player on CentOS 5.4 and its working fine. However it does not allow me to increase the RAM more than 3GB. It keeps throwing error stating- "Requested memory size is greater than allowed maximum of 3072 MB. Could not initiate memory hot plug." I understand from few threads that 32bit OS has this kind of limitation but I am able to understand why I am seeing this issue when I am using 64bit OS and VMware player is also for 64bit. Regards Hersh

glusterfs-server package: what happened to it?
by Florin Andrei 21 Jan '14

21 Jan '14

I'm doing some experiments with GlusterFS. Most documents online suggest to install the glusterfs-package as if it was available directly in the repo, and therefore installable via a simple "yum install". Unless I'm wrong, it appears that this package is not in the repo for CentOS 6. Does anyone know what happened to it? -- Florin Andrei http://florin.myip.org/

mounting CDROM without mapaping UC to LC
by Fred Smith 20 Jan '14

20 Jan '14

Hi! this is surely a newbie question, so I should know the answer, but I'm fighting with mounting a CD such that filenames are NOT mapped to lowercase (I need to use its on-board tools for accessing files on it while mounted on Centos 6.5, and those tools assume uppercawse, since they assume the entire world runs Windoze.) but despite my best efforts, it keeps being mounted with UC-LC mapping enabled. here's what I've been trying: mount -t iso9660 -o norock,remount,ro,nosuid,nodev,uhelper=udisks,uid=500,gid=500,iocharset=utfi,mode=0400,dmode=0500 /dev/sr0 /mnt/cd and even this: umount /mnt/cd mount -t iso9660 -o norock,ro,nosuid,nodev,uhelper=udisks,uid=500,gid=500,iocharset=utfi,mode=0400,dmode=0500 /dev/sr0 /mnt/cd I've also tried using nojoliet both with and without norock, and also map=normal, all to no avail. I also tried the remount option using the original automount location in /media, and got no better results. I'm hoping someone out there can point me to what I'm doing wrong.
