Storage on Stormshear
When we created extra partition for ''arcology'' ZFS pool on Ysul and ''wharf'' LVM group on Dwellers, we have underestimated the overhead of the VMs.
|Ysul||-||Main hard disk||400 G|
|Ysul||T150||ZFS arcology||100 G|
|Dwellers||-||Main hard disk||100 G|
|Dwellers||T166||Wharf for Docker||200 G|
But we have some overhead. For example, it seems Ysul has snapshots enabled (I think this were a safety measure to handle T293), as we have this:
-rw------- 1 root root 94.3G Aug 2 13:07 Ysul-000001-delta.vmdk
-rw------- 1 root root 3.5G Apr 8 19:08 Ysul-Snapshot1.vmsn
-rw------- 1 root root 7.8G Aug 2 13:03 Ysul-zfspool-000001-delta.vmdk
We don't need so much space, as we currently use it for jails and poudriere.
$ zpool list NAME SIZE ALLOC FREE FRAG EXPANDSZ CAP DEDUP HEALTH ALTROOT arcology 99.5G 17.0G 82.5G - - 17% 1.00x ONLINE -
- Destroy the 100G arcology ZFS pool and recreate it on a 25G storage
- Disable snapshot on Ysul - I totally know it's a good idea as it's also a dev machine, and so not totally instrumentable, but we don't have the hard disk to do that. A proper backup strategy and a Tahoe grid is needed.
