Hi Kevin, If you actually ran into a 'read-only filesystem' issue, then it could possibly because of a bug in AFR that Pranith recently fixed. To confirm if that is indeed the case, could you tell me if you saw the pause after a brick (single brick) was down while IO was going on? -Krutika On Wed, May 25, 2016 at 1:28 PM, Kevin Lemonnier <lemonnierk at ulrar.net> wrote:> > Whats the underlying filesystem under the bricks? > > I use XFS, I read that was recommended.

Hi, Not that I know of, no. Doesn't look like the bricks have trouble communication, but is there a simple way to check that in glusterFS, some sort of brick uptime ? Who knows, maybe the bricks are flickering and I don't notice, that's entirely possible. As mentionned, the problem occurs on it's own. I can trigger it faster by using the disk a lot (doing database import) but it occured this night for example and I wasn't using the machine at all. I googled a bit and I found quite a lot of thread on the proxmox forum about this but for older versions of glusterFS. I am using qcow2 usually, just tried with raw and same problem. I just mounted the volume with NFS, and I'm currently moving the disk on it to see if the problem is libgfapi only or if it happens too with NFS.

Also, it seems Lindsay knows a way to get the gluster client logs when using proxmox and libgfapi. Would it be possible for you to get that sorted with Lindsay's help before recreating this issue next time and share the glusterfs client logs from all the nodes when you do hit the issue? It is critical for some of the debugging we do. :) -Krutika On Wed, May 25, 2016 at 2:38 PM, Krutika Dhananjay <kdhananj at redhat.com> wrote:> Hi Kevin, > > > If you actually ran into a 'read-only filesystem' issue, then it could > possibly because of a bug in AFR > that Pranith recently fixed. > To confirm if that is indeed the case, could you tell me if you saw the > pause after a brick (single brick) was > down while IO was going on? > > -Krutika > > On Wed, May 25, 2016 at 1:28 PM, Kevin Lemonnier <lemonnierk at ulrar.net> > wrote: > >> > Whats the underlying filesystem under the bricks? >> >> I use XFS, I read that was recommended.
