Out of inodes on GFS file System

We are running Red Hat 5.5, and our file systems are using GFS...

We have a file system that has run out of inodes... How can this be increased for a GFS file system ??

# gfs_tool df /home/smonitor
SB lock proto = "lock_dlm"
SB lock table = "APSMON:gfs08"
SB ondisk format = 1309
SB multihost format = 1401
Block size = 4096
Journals = 3
Resource Groups = 60
Mounted lock proto = "lock_dlm"
Mounted lock table = "APSMON:gfs08"
Mounted host data = "jid=2:id=393219:first=0"
Journal number = 2
Lock module flags = 0
Local flocks = FALSE
Local caching = FALSE
Oopses OK = FALSE

Type Total Blocks Used Blocks Free Blocks use%
inodes 2580593 2580593 0 100%
metadata 1165229 113033 1052196 10%
data 87714 86975 739 99%

Re: Out of inodes on GFS file System

Looking further, all of our gfs file systems show this 100% on inodes, so I don't think that is an issue....

The df command shows inodes are ok...
# df -i /home/smonitor
Filesystem Inodes IUsed IFree IUse% Mounted on
3633489 2582857 1050632 72% /home/smonitor

The df on the file system shows 73% full, but the gfs_tool shows 99%.... Not sure what to believe any more trying to figure this out..

# df -h /home/smonitor
Filesystem Size Used Avail Use% Mounted on
15G 11G 4.1G 73% /home/smonitor

Re: Out of inodes on GFS file System

WHat option did you use to create your GFS2 filesystem? If you planned on using it for zillions for files -- you should have chosen mail storage or something...

Re: Out of inodes on GFS file System

Hi Mike,

The below Redhat article has explanation about why gfs becomes slow when filesystem is close to 100%. The gfs tool output actually gives the number of resource groups. ==> this article has information on why there is mismatch between df & du outputs.

Found the solution in using command:

gfs_tool reclaim
