Hiya,
I've got a bunch of Solaris 10 servers that I'm supposed to be monitoring.
For reasons that pre-date my arrival on this scene, we've got a number of
filesystem-in-a-file loop-back (lofi) filesystems mounted in one of the
Zones. Ganglia doesn't seem to be able to cope with them.
I've run gmond (in the global zone) with "-d 9" and got the following:
------------------------------------------
...
metric 'part_max_used' being collected now
Counting device /UATWEB3/root/root/dev/lofi/1 (8496.99 %)
Counting device /UATWEB3/root/root/dev/lofi/2 (100.10 %)
For all disks: 14952032.177 GB total, 18299958574.006 GB free for users.
...
------------------------------------------
Firstly, I'm pretty sure we haven't got nearly 15 petabytes of disk on
that server. More like hundreds of gigabytes.
Secondly, I'm fairly sure that even if we had got 15 petabytes total,
there wouldn't be 18 exabytes of that free for users.
Finally, Solaris doesn't think that filesystem is 8496% full (looking
inside the Zone):
------------------------------------------
Filesystem kbytes used avail capacity Mounted on
/dev/lofi/1 6190257 1961227 4167128 33% /www
/dev/lofi/2 6190257 1966687 4161668 33% /www1
------------------------------------------
Has anybody else seen this behaviour, and does anybody have any
suggestions re what to do about it?
Thanks,
David.
