Defrag file system poblem

gigiz — Wed, 22 Mar 2006 08:13:48 GMT

Hi ,
I have a big problem ...
I have ha file system:
1600 Gb total
1100 Gb used
one Vg
one lvol
23 disk
I wanted recover any disk for another vg from that
I started :
/usr/sbin/fsadm -d -D -e -E /file_system

The problem is that now they are 24 hours and the fsadm not finished.
I would want to know if :
How can calculate a remaining time
i can kill fsadm process, how kill that, and the impact... it is dangerous

Hi gigiz,

You savely kill the fsadm defragmentation, but I don't understand "wanted recover any disk for another vg from that"

# ps -ef | grep fsadm
# kill pid

Shalom,

It is dangerous to kill the process. That being said, I had an operator once boot a system while this was running and no data was lost. its well designed or we were lucky.

Calculating the time depends on how busy the disks are. It will go faster on an idle system.

Best practice is to let it run and schedule future runs for a weekend.

Also the next time you run fsadm for defragmentation purposes on your filesystems, specify the "-Fvxfs" switch so that it doesn't traverse NFS mounts.
