[Linux-cluster] gfs2_tool unfreeze hang

[james pedia]

Noticed this thread for the same issue at:

https://www.redhat.com/archives/linux-cluster/2012-September/msg00084.html:

I think I hit the same issue:

(CentOS6.3)
# uname -r
2.6.32-279.el6.x86_64

gfs2-utils-3.0.12.1-32.el6_3.1.x86_64 is in use here.


# gfs2_tool freeze /var/www/html
# ls -l /var/www/html/
total 8
-rw-r--r-- 1 root root 10 Oct 30 23:47 a
-rw-r--r-- 1 root root 41 Oct 30 20:44 index.html
# cp /var/www/html/a /var/www/html/b
(HANG HERE)

Then try this:
# gfs2_tool unfreeze /var/www/html
(HANG AS WELL)

The whole cluster has to be reset to recover from this.

'dmsetup suspend' and 'dmsetup resume' are working fine.

Are these commands basically doing the same thing ('dmsetup suspend' vs
'gfs2_tool freeze')?

Is there a way to see if GFS2 file system is currently being suspended or
frozen?

Thanks,
