Re: [Linux-cluster] GFS2 volumes hanging on 1 of 3 cluster nodes



Hi Heiko,

I'm using Dell R310's for this setup, which indeed have broadcom NIC's. I've emailed Dell Prosupport for the location to the latest firmwares ( that site is a mess :( ). In the meantime, could you tell me how you figured out that the NIC's were to blame? What symptoms did you see? Something else i can check to see if it's indeed the same issue?

I reformatted the gfs2 filesystems with default 128M journals, just in case that helped. I can now see all gfs2 mounts on all 3 servers. I went on to start clvmd on every node, 2 nodes went fine, 3rd node gave a timeout. All lvm based commands on that server now hang, on the others those commands work fine.. *sigh*.

Kind regards,

Bart

Which hardware are you using for your setup? I am just asking because
I have experienced similar problems which finally have been solved by
updating the NIC firmware of the systems involved (Dell R610 with
Broadcom NICs).

Hello,

I've set up a 3-node cluster, where i seem to be having problems with some of my GFS2 mounts. All servers have 2 gfs2 mounts on iscsi luns, /var/lib/libvirt/sanlock and /etc/libvirt/qemu.

/dev/mapper/iscsi_cluster_qemu on /etc/libvirt/qemu type gfs2 (rw,relatime,hostdata=jid=0) /dev/mapper/iscsi_cluster_sanlock on /var/lib/libvirt/sanlock type gfs2 (rw,relatime,hostdata=jid=0)

Currently, on vm01-test, i cannot go to /var/lib/libvirt/sanlock:

root vm01-test:~# ls /var/lib/libvirt/sanlock
^C^C^C
^C
^C
