cleanup & base snapshot in SnapVault

cjeff — Thu, 05 Jun 2025 07:04:49 GMT

IHAC just upgraded their FAS3020 to FAS2040 as the SnapVault secondary, now they found that there are some cleanup & base snapshots exist after the reboot, they want to know whether these snapshots can be deleted, and want to know why these snapshots exist? Below is the example:

Volume sv_naana004_nkg

working...

date name

------------ --------

Nov 20 02:01 sv_nightly.0

Nov 20 02:00 naana030(0135106925)_sv_naana004_nkg-base.0 (busy,snapvault)

Nov 19 02:00 sv_nightly.1

Nov 18 02:06 sv_nightly.2

Nov 17 02:30 sv_nightly.3

Nov 16 02:17 sv_nightly.4

Nov 15 01:48 sv_nightly.5

Nov 14 09:14 naana030(0101200566)_sv_naana004_nkg-base.0

Nov 14 09:13 naana030(0101200566)_sv_naana004_nkg-cleanup.0

Nov 14 01:54 sv_nightly.6

Thanks,

Base snapshot name includes filer sysid, so it is quite possible that changing hardware (i.e. getting new sysid) will generate new names for base snapshots. What I am not able to find – how SV base snapshots are structured (it could be described in paper training material which I do not have right now). For SnapMirror snapshot name includes destination sysid, which corresponds to secondary for SV.

I do not know what –cleanup snapshots are.

My guess would be, those snapshots can be removed, but let’s wait for someone with more SV experience to chime in ☺

aborzenkov, you are right. changing a sysid will generate "homeless" base snapshots which need to be deleted manualy.

BTW with "snapvault status -l" you see the currently used base snapshot for your snapvault relationship.
