Increase FS

[Mag0007]

I am trying to increase my /tmp filesystem

using AIX 5.3

there are a total of
FREE PPs: 98 (3136 megabytes)

I am doing chfs -a size=+1 /tmp

and I get this error

0516-634 lquerypv: /tmp directory does not have enough space,
delete some files and try again.
0516-848 lquerypv: Failure on physical volume , it may be missing
or removed.
0516-788 extendlv: Unable to extend logical volume.

1. Your LV for /tmp may not have enough partitions. Check and increase if needed.

2. /tmp is 100% and cannot increase because chfs will use /tmp temporarily. Delete files that are not needed.

3. /tmp doesn't exist?

You probably need to extend your logical volume first.

- extendlv hd3 1 (extend you logical volume by 1 PP)

-lsfs -lq /tmp
The output should look something like this:

Name Nodename Mount Pt VFS Size Options Auto Accounting
/dev/hd3 -- /tmp jfs 229376 -- yes no
(lv size: 229376, fs size: 229376, frag size: 4096, nbpi: 4096, compress: no, bf: false, ag: 8)

find the lv size in the bottom of the output, you need this number to ncreas the filesystem.

chfs -a size=[LVsize] /tmp

Your /tmp should now be larger.

No you do not have to increase LV first, chfs can/will take care of that, but you need some free space in /tmp in order for chfs to succeed.

I'm guessing that /tmp is 100% full???

You need to delete some files in /tmp first (or move them to another filesystem (e.g. /var/tmp) if you don't want to lose any of the files in /tmp or if you are not sure which files to delete)

There is a point at which you will not be able to increase /tmp without first increasing the lv physical partitions. However, the default is 512 - I believe and depending on your pp size - that is pretty large. I would suspect that your /tmp is full - like the others have said. /tmp should be a receptacle for only work type files - no permanent files of consequence so you ought to be able to clean it out. I have a script that cleans it every time I reboot so that I don't have to worry about whether a file is being created while I am trying to delete it - a bad thing!
