Identify disk by ID, not system name

[cluelessperson]

Example

/dev/disk/by-id/ata-HGST_<MODEL>_<SERIAL>

instead of

/dev/sda

which changes on reboots and such.

I would like this change very much. I've seen spurious false positives after device names change. This is possibly a linux issue, so it should be checked if the machine is running linux first. I'll try to fix it myself, perhaps…

I just posted a pull request for this

[bbrendon]

Great idea.

I suggest by-path, not by-id, because one can change sata hot swap disk daily to take backups.
Same disk path, but different disk id.
Path never changes.

[cluelessperson]

Agreed

I still like by-id better, since if you were to accidentially reorder the disks, they stay the same. Also, I would never use hotplugging disks for backup. Backups go over the net.

[gabviv73]

I would be nice to have a config entry to choose from by-id, by-path.
We use hotplugging to take backup media offsite manually.

I fully agree that this pull request is important, as the disk enumeration changes too often between reboots. Also, if there is historic data, e.g. temperature, it's difficult to track a specific device when the identifier changes.

I noticed this is marked as an "enhancement" I suggest it's more of a bug.

[rkarlsba]

I don't know why this hasn't been pulled. The code is rather straight-forward.
