Using 7.10.2 Basic licence
After let my snapshot file system run out of space (100% full), I face the error were no more daily snapshots could run. This file system has nothing but snapshots, so I couldn't delete other files.
Trying to delete some older snapshots also failed with "no space let on device" error.
Adding other disc or somehow increase available space was not an option here, so I pick some
snapshot files to delete. That's what I did:
On configured repository mount point, deleted these two files with system date that match an old snapshot date:
and on indices subdirectory, deleted all folders with same system date.
After that, I deleted one more old snapshot, using Kibana's Snapshot and Restore. No errors occurred and both deleted snapshots are no longer listed in Kibana's Snapshot and Restore snapshot list.
Snapshot file system is now 80% used
Adjust your snapshot Policy (ex. retention days) if needed to avoid future problems.
I'm not sure if this procedure can be replicated or if was just luck to have file system dates that match snapshot dates. Does anyone tried this approach?
