arg, what a weird one... i have a tiny desktop i setup as a miniserver with mirrored zfs ssds. two decent samsung EVO's 500G. i just had one go offline for a few days, 300+ write errors and it's degraded. smartctl wouldn't dump any info. suddenly smartctl works again but i haven't rebooted or reset the hardware. should i attempt a zpool clear?

i was thinking of trying to swap out the sata cable hot since it's already technically offline. just not sure if camcontrol rescan is enough

similar thing has happened to me, both on beelink EQ12 I think it is, and on a Deskmini i think it's called. Crappy little sata connectors. Makes me want to go with nvme, or at least m.2, only for mini pc's. i tend to take it apart, put it back together, and hopefully everything is fine after a zpool clear and/or resilver

yeah, well... this is mirrored boot. i just replaced an offbrand secondary disk with a second evo

i thought i setup the boot sector and copied over the efi files

i really didn't want to get in a reboot test ;]

i'm now running on the replaced drive, it's the primary that failed. it does sound like a connector

i have a new sata cable... if this were AIX i'd just rmdev -l hdiskX, and service the hardware

i'm considering a camcontrol stop on that disk, and go hot rewire it

and then a camcontrol rescan

to see if it comes back
