Re: Broken? snapmirrors - how to delete them ?

hardy_maxa · ‎2014-02-03

Hi all

On my filer, I was doing some backup testing, and now have these snapmirrors showing, which I can't delete

aushafs2b> snapmirror status

Snapmirror is off.

The first 4 entries are fine - they are my mirrors between systems.

But I want to cleanup the last three.

As far as I can tell, there are no backup or smtape sessions still active.

Thanks,

Hardy

Use "snapmirror release" to remove old SnapMirror snapshots. You may also need to remove them from snapmirror.conf.

hardy_maxa · ‎2014-02-03

Thanks - This worked on the smtape snapmirror entries, but the not those still displayed in the output (above)

Any other ideas ?

Use snapmirror release srcpath dst_filer:dstpath command to release the snapmirror relationship from source filer.

aborzenkov · ‎2014-02-04

Check if you have leftover snapmirror snapshots on destination - manually remove them (they should be unlocked after snapmirror break). Those snapshots are not removed automatically.

lhoffman1 · ‎2014-02-04

Can you show us the output from "snap list" admin / images and domino2_vol ?

If you have no orphaned records within the "snapmirror.conf" file, you have some relations within old snapshots.

btw. I wonder, your snapmirror is set to off, although your idletime is not so old.

working...

No snapshots exist.

I think snapmirror was set off when I noticed the issue.

Now though, it is on.

aushafs2b> snapmirror status

Snapmirror is on.

aborzenkov · ‎2014-02-04

For images it should be enough to remove leftover snapshot “aushafs2b(1785237204)_images.1109”. Others two are really interesting. Could you post output of “smtape status -l”?

hardy_maxa · ‎2014-02-04

Not much - it just says "job not found"

SHARMAMANISH · ‎2014-02-04

Can you send me the output of options snapmirror.enable

MOHIT_FUJITSU · ‎2014-02-05

Can you post the output of "snapmirror status -l" ?

hardy_maxa · ‎2014-02-05

Here's all the snapmirror options

aushafs2b> options snapmirror

snapmirror.access legacy

snapmirror.checkip.enable off

snapmirror.delayed_acks.enable on

snapmirror.enable on

snapmirror.log.enable on

snapmirror.vbn_log_enable off (value might be overwritten in takeover)

snapmirror.volume.local_nwk_bypass.enable on

again: pls output the command:

"snapmirror status -l aushafs2b:domino2_vol aushafs2b:nrst1a"

thx

hi all,

go to designation end follow the below steps,

snapmirror status-- check it is snapmirror on status (continue follow steps)

which u want to remove entry in this output ensure.

snapmirror break designation volume

goto ---> rdfile /etc/snapmirror.conf --take this output in notepad

in notepad output--> which line of snapmirror you want to remove ensure and put # comment symbol.

wrfile /etc/snapmirror.conf--> paste the commented output and ctrl+c to save and exit

now u can run snapmirror status all should be clear.

hardy_maxa · ‎2014-02-10

Thanks, but this doesn't help either

aushafs2b> snapmirror break aushafs2b:nrst1a

snapmirror break: nrst1a: destination is offline, is restricted, or does not exist
