Lost files + indentical Foldernames on XFS Partition

Lost files + indentical Foldernames on XFS Partition

[Steffen Knauf]

Hello,

today i have a strange behavior. I have a a directory which contains 
lots of indentical Folders with the same Name and Inode.
I don't create Hardlinks or something else. On the other side some files 
are suddenly vanished. A "ls -al" result in the following error: 
"Access  to bla not possible: File or Directory not found."
I don't find some Errormessages in the logfile. I don't know whether a 
xfs_check make sense.

greets

Steffen

What kernel?

Can you cut and paste what you see?

xfs_repair -n will check the filesystem without actually modifying anything.

Linux version 2.6.16.60-0.21-smp (geeko@buildhost) (gcc version 4.1.2

Really strange is that if execute only a 'ls' command the files are 
shown twice:

combine_sbn.0051.tga
combine_sbn.0051.tga

But if i execute 'ls -il' the output looks like this:

combine_sbn.0051.tga: Datei oder Verzeichnis nicht gefunden
combine_sbn.0057.tga: Datei oder Verzeichnis nicht gefunden
combine_sbn.0058.tga: Datei oder Verzeichnis nicht gefunden

Here a directory example:

2147642598 drwxrwxrwx 2 500 500 4096 2009-03-17 12:33 
S14-01_Fische_beauty_Main
2147642598 drwxrwxrwx 2 500 500 4096 2009-03-17 12:33 
S14-01_Fische_beauty_Main

Would probably be good to try an upstream kernel to see if it persists,
if you can; otherwise for an older distro kernel like this, a report to
SuSE would be in order.

so the filename is in the directory but doesn't point to a valid file I
guess.

You could also create an xfs_metadump to save for later investigation.

Does this happen on the filesystem you mounted in parallel on two machines?
I remember your question from early this week, so I ask

Yes, but i mounted the partition only a short time parallel (we only 
read from this partition). At the moment, the mounted Filesystem is only 
mounted on one machine.

oh... well in that case, do an xfs_repair before anything else.

Yes, i'll do this in next days, but the Partitions are very huge ( 5 TB).
I think that will take a while. Till then, greets and thanks!

I unmount the partition, but if i try to use xfs_repair, i get the 
following error:

xfs_repair: /dev/sdc3 contains a mounted and writable filesystem

fatal error -- couldn't initialize XFS library
