There is only nightly backups and my mac time machine backups on the pool so I have a bit of time

@[email protected] @[email protected] The program for disk recovery I used was something that works at the disk sector level. It's called ddrescue I think, and has nothing to do with dd. It's brilliant. It creates a map file of your disk's sectors, then repeatedly tries to read sectors, forward, backwards, random read, for hours on end. It keeps its progress in the map file so you can cancel and resume it at any stage, and it applies different methodologies to try to scrape data back from a dying drive. #linuxtip
I have a machine that boots Proxmox from a zpool mirror. One of the drives failed and it took the whole machine down. Upon rebooting it tried to mount the zpool but failed and landed me at a uboot prompt.
Disconnecting the failed drive allowed the machine to boot just fine (with a degraded pool).
What happened ? I thought the point of a mirror was to gracefully survive a disk failure.
