Good day Guys
We just had an issue on one of our clients servers, whereby the server was
claiming there was no more space, but df showed there there plenty of space
(even checked the inodes).
We were really stummped, but after Googling around, the following command
was needed to be run tunefs.ocfs2 --fs-features=discontig-bg /dev/drbd0
Here is the output before tunefs.ocfs2 was run
user at server:/storage/www/site.com/current/sites/default/files/tmp$
<http://daddysdeals.co.za/current/sites/default/files/tmp$> df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 10G 302M 9.2G 4% /
udev 10M 0 10M 0% /dev
snippet removed
/dev/mapper/vg1-storage 99G 2.5G 91G 3% /storage
/dev/drbd0 100G 43G 58G 43% /storage/shared <= Look here.
The question I would like to ask. Is this a feature I can safely just roll
out, across all servers? If so, what are the complications.
Or should I just consider this a feature, and be glad this happened and let
things be.
The other question I would like to ask is, generally we nagios the crap
out of servers.
This one slipped through the cracks, would anyone know for what flag or
variable I need to look out for.
I tried the suggested debugfs.ocfs2 -n -R "stats" /dev/drb0.
But I can't see what I need to check for (I compared debugfs.ocfs2 across
various servers.)
Thank in advance.
Regards
Brent Clark
