AIX

Last time system rebooted 57 days back.

yes, there are errors in errpt but no error is related to /home filesystem.

I don't use AIX so take this with a grain of salt... If I understand, hd1 is a logical volume that contains /home but it appears that /home is too small. With other OS's, taking HP-UX as an example, there is an lvextend command to grow a logical volume and there is an extendfs command to grow the filesystem. And it is possible to run the former and forget the latter, thus creating this very situation. Maybe that happened here?

Thanks to all for help, this problem has been fixed now.

Acutallly rather than using chfs -a size+XXX /home to increase filesystem size, the command extendlv has been used instead. i.e. extendlv XX hd1

The output of lsfs states that the filesystem size is blocks is: 6291456 blocks

A filesystem of 1PP of 64MB has 131072 512 byte blocks, so the following command showed that the filesyetem is only using 48 of the 200 PP.

#dc
6291456 131072 / p
48

so, the problem is fixed by using following commands to use all the space that had been allocated:

chlv -x 200 hd1
chfs -a size=12800M /home

Thanks
