**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. | **Server** | **Task** | **Description** | **Size** | 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 | **Total** | . | . | **800 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 **Ysul arcology** 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 - ``` **Plans** * 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.
