Quick question: you're not running xfs_freeze are you?
If so, try without, as device-mapper does the equivalent of that
internally and xfs can't handle things if it gets run twice.
No, if I run xfs_freeze first, lvcreate hangs when it tries to suspend
the volume, so I stopped doing that.
Now, if I run lvcreate shortly after the machine is booted, it runs
successfully. However, if I try to run the same command the next day,
after it's been online and the webservers have had the filesystem
mounted, it hangs when trying to suspend the volume.
Is it possible that mounting the NFS mounts on the webservers read-only
as a temporary measure while creating the snapshot will help?
So I'm wondering if the problem is that the webservers have the
filesystem mounted and in use (apache is serving pages from it), I'm
trying to find a way to keep the filesystem mounted over nfs but still
be able to create snapshots, and I was wondering if I could use
xfs_freeze and have lvcreate not try to suspend the volume.
Thanks,
Kristina
