Hi,
Whilst running xfsdump on our serve, NFS crashed and couldn't be
restarted. The output from /var/log/messages is shown below. I've read
that ext2dump shouldn't be used with 2.4 kernels - does this apply to
xfsdump?
Any time I see a NULL pointer being de-referenced, I get worried...
I am running kernel-smp-2.4.2-SGI_XFS_1.0 from the Red Hat 7.1 SGI XFS
install CD.
Cheerio,
Paul
