How safe to Kill fsadm -d -v -e /oracle----- URGENT

[$t!$-]

I Have started defragmentation of a large file system wthout time frame. Can anyone suggest me , is there any possibility of data loss to kill fsadm -d -v -e /oracle.

Hello,

There is always the possibility of data loss with any disk-related administrative task. This is why good backups are essential. This is also why it's important to schedule such operations during the off-hours.

Chances are, there will be no data loss, but there is no guarantee. I recommend letting the defrag operation finish.

In the future, set a time limit with the '-t ' switch to 'fsadm', or a passes limit with the '-p ' switch. 'man 1m fsadm_vxfs' for more information.

Unless you have a compelling reason to stop it, I would let it run. When you phrase the question "is there any possibility of data loss", there can be but one answer: YES. If you change "any possibility" to "any probability" then the answer becomes: Yes, but it is very small. I certainly would not throw a kill -9 at it but you could try a kill -15.

In general, I have found it very difficult to measure any gains (much less significant gains) from the defragging operation and especially on Oracle filesystems where the files tend to be pre-allocated.

I would never recommend a defrag on a PROD file system.if at all you wanted try "kill -15" you take one more backup before that..

hi,

Unless this is impacting on your performance, it would be wise to wait for the process to complete.

Otherwise, you can kill the process. At most, the Oracle instance will crash. But then on the restart of the database, it will recover automatically.


good luck!
