[Xen-devel] Re: [Xen-users] kernel error messages with 2.6.16: XFS internal error xfs_ialloc_read_agi at line 1357 of file fs/xfs/xfs_ialloc.c

[Patrick Wolfe <pwolfe@xxxxxxxxxxxxxx>]

I use the XFS filesystem all the time.  I'm running it on both dom0 and
domU on several machines, and have had absolutely no problems.

The error messages you included indicate a corrupt filesystem.  I'd try
standard stuff - dismount it, run fsck on it, and try again.

Also, make absolutely sure that filesystem is only being used by ONE
system, real or virtual.  You can't mount an XFS partition read/write by
multiple systems, or you'll have corruption problems like this.
