Broken? snapmirrors - how to delete them ?

hardy_maxa — Thu, 05 Jun 2025 05:44:07 GMT

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.

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.

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 — Tue, 04 Feb 2014 13:26:45 GMT

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.

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”?

Re: Broken? snapmirrors - how to delete them ?

Not much - it just says "job not found"

Re: Broken? snapmirrors - how to delete them ?

SHARMAMANISH — Wed, 05 Feb 2014 07:02:20 GMT

Can you send me the output of options snapmirror.enable

MOHIT_FUJITSU — Wed, 05 Feb 2014 09:50:30 GMT

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

Re: Broken? snapmirrors - how to delete them ?

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.

Thanks, but this doesn't help either

I know its not windows, but what about a reboot ?

Re: Broken? snapmirrors - how to delete them ?

YEKYAWTHARMYINT — Tue, 11 Feb 2014 09:14:43 GMT

Hi Hardy,

Have you already tried snapmirror release from aushafs2b?

Re: Broken? snapmirrors - how to delete them ?

lhoffman1 — Tue, 11 Feb 2014 10:59:40 GMT

No, a reboot doesn't help. I think the problem is on Backup Server side, not filer.

But.. you are set the mirror from aushafs1b to aushafs2b .

What about the snapmirror status from aushafs1b ? and the "snap list admin" by aushafs1b ??

Re: Broken? snapmirrors - how to delete them ?

hi,

aushafs2b:images aushafs2b:NDMP_LOCAL_005617 Source - Idle

aushafs2b:domino2_vol aushafs2b:nrst1a Source - Idle

this should be source. please follow my steps in designation end.

can please share the below output from dst end.

snapmirror status

df -Vh nrst1a

lun show -l nrst1a

rdfile /etc/snapmirror.conf

lun show unmapped

one more Question this replication within filer or across the filer?
