It happens all the time...
If you run "camcontrol identify ada0" (or whatever your device is) you can find out before it is too late:
sector size logical 512, physical 512, offset 0
This is from a lucky drive of course :)
- StavrosK 14y agoHmm, there's no such command in Ubuntu, maybe it's from BSD?
- olgeni 14y agocamcontrol is from FreeBSD. I don't have a Linux box available right now but maybe "hdparm -I" does something similar: "request identification info directly from the drive".
- StavrosK 14y agoYep, that works: Logical Sector size: 512 bytes Physical Sector size: 4096 bytes I'm guessing that's not very nice. My ZFS pool was created with ashift 9 (this is 2^9=512 bytes), when it should be 12 (2^12=4096). I will have to copy everything off and back on again. For everyone who wants to check, and because I couldn't find info on it, run: zdb | grep ashift And see if it's 9 or 12.
