SGI is no longer the maintainer for XFS in the open source community.  XFS is maintained by Dave Chinner<br>

and developed and enhanced by a large community of contributors.<br>

<br>

Reference the manpage for the xfs_freeze command to help stabilizing your filesystem before<br>

generating a snapshot.   Quoting the manpage, "xfs_freeze is intended to be<br>

used with volume managers and hardware RAID devices that support the creation of snapshots."<br>

<br>

Thanks,<br>

Troy McCorkell<br>

<p class="MsoNormal"><span style="font-size:14.0pt; color:black" lang="EN-US">I’m trying to backup XFS partition SUSE 12 with XFS_PROGS 3.2.1, when we do snapshot of the partition. The created snapshot always have problem by run “xfs_repair –n /dev/VG/snapshot”.

 I have tried “sync” didn’t flush cache to disk. Then tried to umount and mount the XFS partition the snapshot looks fine. Can you tell me another way to force XFS flush cached data to disk?
