June 22, 20233 yr Upgraded from 6.11.5 to 6.12.1, have two 500G drives for basic array (Data and Parity) and then a ZFS pool for most of the storage. 6 x 8TB drives in a single zDev on raidz1. Also have 4 x 200G SSDs (Oracle F80 PCIe card) acting as my zfs cache. I cannot for the life of me get the zfs to appear properly in the GUI. I figured out the first issue was my mount point (I was using /tardis not /mnt/tardis before). I exported and reimported it, and changed the mount points. So I fixed that, but it still won't show usable space in the main array display, but zfs master shows the pool as imported and I can browse the pool on CLI. See screenshots for how I have the pool configured in the GUI, zfs master status, and the output of lsblk and zpool status. Thanks in advance for any assistance. tardis-diagnostics-20230622-1124.zip
June 22, 20233 yr Community Expert Solution You need to assign all pool devices (including cache) to the same Unraid pool, also note that the pool fs must be set to auto, so unassign all devices, start array, stop array to reset the pool, change slots to the correct number, assign all pool devices, don't change the pool filesystem, leave it set to auto, start array.
June 22, 20233 yr Community Expert Forgot to mention, you also need to export the pool first, or it won't work: zpool export tardis

June 23, 20233 yr Author So I'm having other issues now. The zpool was imported without compression (I had it on when I stood the pool up). I enabled it, and noticed while my pool is back, multiple datasets are now just empty. zfs list shows the dataset as having 16.6T used but nothing is in the directory. I attempted a scrub, but it didn't change anything.
June 23, 20233 yr Author I figured it out. The sharenfs flag was enabled on the dataset (for some reason) and I found other posts that mentioned this as an issue. Disabled it, rebooted and I see the files
