Unhappy reiserfs filesystem


Hi there,

I am using kernel-iamge 2.20 and was trying to mount resierfs filesystem but I was told that 2.20 will not support resierfs file system so I installed kernel-iamge 2.20-reiserfs ( apt-get install kernel-image-2.20-reiserfs). Everything worked fine after that. I was able to mount my filesystem. But strang thing happen last night. I mounted the fileststem and in turns it gets mounted by another AIX server as nfs mount and it write filesto that disk but somehow it faid as it looks for some files on this disk and then write to it but the disk was empty.
I don't know how it gor empty or formatted . I tried to umount ( on local debian box) and remount but it started giving me bad fs type, boad super block error.
Otday morning it tried to mount another disk and it got mounted without error. I am afraid that if I mount another disk with data, will my disk gets formatted. If yes then WHY and I ma totally confused to what to do. Why and data was lost??

Any suggestions.

Thanks

The bad fs type errors could have been caused by a fsck needing to be run. Has that machine crashed or shut down improperly? In your fstab is it mounted with 'defualts 0 0' or 'defualts 0 2' The first will mount it with out doing a fsck after a crash, the second will.

The disk appering empty could be caused by permissions, on the local machine change the permissions on the mount point to allow access, I usally use "chmod a+rw /mountpoint"

Yes at first the options on fstab were rw,user 0 2. But now I changed it to
defaults,nosuid,nodev,auto.
I mounted another disk and trying to write to it from NFS mounted directory from other AIX system.
What I need is every night the AIX server should mount this disk (/de/hdd1) on debian box and write backup to it.
HELP!!!!

Thanks

I checked the kernel log and I see that whenever it mounts reiserfs fs, sometimes it says that using r5 hash to sort name and once it syas using tea hash to sort name.

Does it makes any difference ??

I don't think the r5 hash is the problem.
I have had this happen befor. I should have asked you to check the permissions on the AIX box for the mounted nfs directory. Since it is mounted as root another user may not be able to acces it, so you will have to adjust the permissions on the AIX box to allow access to that directory.
