[Linux-cluster] gfs_controld plock errs

[nick at javacat.f2s.com]

Hi Folks


RHEL 5.2

gfs2-utils-0.1.44-1.el5_2.1
kmod-gfs-PAE-0.1.23-5.el5
gfs-utils-0.1.17-1.el5
kmod-gfs2-PAE-1.92-1.1.el5

5 nodes in a cluster just using GFS over iSCSI.

Were getting the following error in /var/log/messages -

Feb 11 09:17:00 finapp1 gfs_controld[7084]: plock result write err 0 errno 9
Feb 11 09:17:08 finapp1 gfs_controld[7084]: plock result write err 0 errno 9
Feb 12 13:02:25 finapp1 gfs_controld[7084]: plock result write err 0 errno 9
Feb 12 13:02:32 finapp1 gfs_controld[7084]: plock result write err 0 errno 9

And the users are complaining that Oracle occasionally runs slow.

Could anyone help to explain what these errors mean please ?

Thanks,
Nick .
