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

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

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!

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.

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

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.

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

What kernel?

Can you cut and paste what you see?

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

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
