[opensuse] xfs in openSUSE 11.2 vs. in 10.3
I have a user reporting that when they format xfs disks under openSUSE 11.2, they cannot use them on openSUSE 10.3. Could there be some default in 11.2 that is not compatible with whatever the defaults were in 10.3? I am trying to get more details and to see if this can be recreated locally. Any other xfs users out there who move disks between openSUSE releases?

Have a look in /proc/filesystems on each machine to see whcih modules for filesystems have been loaded. Or use lsmod. If its not there, use 'modprobe xfs' If you don't have the module compiled in or loaded at boot time or manually then you can't use a file system. [I say this without access to an 11.2 or 10.3 system. Perhaps they didn't have XFSD at all? I recall using XFS on 11.2 though.] -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Both systems have xfs installed and use this file system regularly. If they format the xfs disk on 10.3 they can use it on 10.3 and 11.2. They are claiming that formatting on 11.2 and using on 10.3 is the problem.

Is XFS used exclusively? Could it be there is a problem with inode size on EXT2/EXT3 that is being attributed to XFS? IIRC, somewhere in that transition from 10.3 to 11.2 the EXT2/EXT3 default inode size was changed from 128 to 256, which older kernels don't understand. -- "The wise are known for their understanding, and pleasant words are persuasive."

No. The 10.3 systems are, however, diskless, booting over pxe. They were made with KIWI. The other file system is in memory. It is at base an ext3 system. The xfs disks are in removable bays and are mounted when the system boots. Has been working great. The xfs disks are formatted elsewhere in a regular openSUSE system. The problem is that the station where they are formatted was upgraded from 10.3 to 11.2. This is when the problem started. How can I find out the value of this parameter for a specific disk? I would of course have to do it on the system where it works. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.

Inode size is 3rd to last line of tune2fs -l output for EXT2/EXT3. I have no idea if there's any relevance to this for XFS, a filesystem type I've never used. -- "The wise are known for their understanding, and pleasant words are persuasive."

I don't know of the xfs equivalent. But, as one might expect, tune2fs does not like xfs systems: tune2fs 1.41.9 (22-Aug-2009) tune2fs: Bad magic number in super-block while trying to open /dev/sda1 Couldn't find valid filesystem superblock And all the xfs* on my 11.2 system are related to the X font server...

ext3.

http://linux.die.net/man/8/mkfs.xfs mentions backward compatibility a few times. In particular, the bit about extended attributes might be worth studying. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Indeed there are such references. Thanks for the pointer. I will have to dig up a 10.3 system and see in the man page there has anything different for those options when compared to 11.2. I am trying to get the user to provide more info on what happens when it fails. Always a good thing to have.
