sector change after growing ?

[Rémi Cailletaud]

Hi,

I face a strange and scary issue. I just grow a xfs filesystem (44To), 
and no way to mount it anymore :
XFS: device supports only 4096 byte sectors (not 512)

xfs_check /dev/vg0/tomo-201111
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_check.  If you are unable to mount the filesystem, then use
the xfs_repair -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.

xfs_repair -L /dev/vg0/tomo-201111
xfs_repair: warning - cannot set blocksize 512 on block device 
/dev/vg0/tomo-201111: Argument invalide
Phase 1 - find and verify superblock...
superblock read failed, offset 1099511623680, size 2048, ag 1, rval -1

fatal error -- Invalid argument


I  don't think i did a mistake, my conf is as follow :

LVM : 3pv - 1vg

the lv containing the xfs system is on several extents :

   tomo-201111 vg0  -wi-ao    1 linear  15,34t /dev/sda:5276160-9298322
   tomo-201111 vg0  -wi-ao    1 linear  18,66t /dev/sdb:0-4890732
   tomo-201111 vg0  -wi-ao    1 linear   8,81t /dev/sdb:6987885-9298322
   tomo-201111 vg0  -wi-ao    1 linear   1,19t /dev/sdc:2883584-3194585

before growing fs, I lvextend the vg, and a new extents on /dev/sdc was 
used. I cant think it caused this issue...

Any idea ?

Cheers,
rémi
