Yeah, I did set it manually before rebooting the OST (see my first
mail). Because it was written everywhere that I could activate the OST
again, I didn't thought much about it. Also the 'lctl conf_param  
homefs-OST0002.osc.active=1' didn't return any error.

In the meantime the file system is fully working again. See my previous
mail.

Anyway here the config:

lustre01 ~ # tunefs.lustre --print /dev/sde
checking for existing Lustre data: found CONFIGS/mountdata
Reading CONFIGS/mountdata

   Read previous values:
Target:     homefs-MDT0000
Index:      0
Lustre FS:  homefs
Mount type: ldiskfs
Flags:      0x5
              (MDT MGS )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters: failover.node=10.1.140.2 at tcp mgsnode=10.1.140.2 at tcp
mdt.group_upcall=/usr/sbin/l_getgroups


   Permanent disk data:
Target:     homefs-MDT0000
Index:      0
Lustre FS:  homefs
Mount type: ldiskfs
Flags:      0x5
              (MDT MGS )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters: failover.node=10.1.140.2 at tcp mgsnode=10.1.140.2 at tcp
mdt.group_upcall=/usr/sbin/l_getgroups

exiting before disk write.
