hello dave hello list,

an unclean shutdown on of my boxes made the xfs partially corrupt.

i tried an xfs_repair with xfsprogs 3.1.10
then i read the corrupt data thread and tried it with 3.2.1 version of xfsprogs.

when i mount the partition and do an ls -l i get:

 # ls -l /mnt/temp
ls: Zugriff auf /mnt/temp/serien nicht mÃglich: Die Struktur muss
bereinigt werden
ls: Zugriff auf /mnt/temp/dokutv nicht mÃglich: Die Struktur muss
bereinigt werden
insgesamt 0

??????????  ? ?     ?            ?             ? serien

the above lines with ls says "access not possible on serien and
dokutv, structure needs cleaning.

This is also after an xfs_repair -L /dev/sde1

is there any trick to get the data accessable again?

thanks for any hints or help

marko
