AIX

Dear All,
I am working on AIX 5.2, and I have allocated 3072M disk space to /home filesystem. Now system has no free space at /home filesystem. But when I checked data on /home, I have only 900M data. Please if anybody can tell me about this difference and how this can be resolved.

Thank You.

Please run a df command and paste the result here. Also take a listing of rootvg (where I trust /home resides) use the command lsvg -l rootvg. Also lsvg rootvg. Paste all out put on your reply.

# lsvg rootvg

This does not add up!

Your rootvg shows that the PP size is 64M and /home mounted on rootvg has 200 PPs. Therefore 200 * 64 = 12800 means you should have a filesystem which has 12.8GByte. Yet your df -m shows you have a /home filesystem which has only 3GByte. Something very peculiar here. The only thing I can see which is questionable is the Quorum being set to 2 when this is a single disk VG (I trust). Please run the command lspv | grep rootvg and paste the result here. What is this machine used for Oracle or something similar? I noticed the raw devices. Are there any other disks?

# lspv|grep rootvg
hdisk0 000cec8e2ce9663e rootvg active

yes we have total 3 HDs installed in this system.

# lspv
hdisk0 000cec8e2ce9663e rootvg active
hdisk1 000cec8ec654d5ba datavg active
hdisk2 005b68ec33ac7a01 datavg active

We are using this server as database (oracle) and application server.

This still makes no sense. I have 2 questions and 1 request. The question when was the machine re-booted last? Are there any errors in the errpt? The request; is it possible to have an ls -l listing of /home? You are 9G adrift somewhere!

Are you using any type of fs manager that pools your data and then splits it into your mount points?

ie.. on our old digital platform we used advfs which pooled say 90gb but we could allocate 30gb across 3 mount points.
We found a reporting bug.. in that if one of the file systems reached 100%, even after cleaning up data, the df command did not report the free space.

Its possible that the native OS could have a similar reporting bug.
