comment Do you lose everything when you have a hard disk failure in a multi-hard disk LVM that does NOT use RAID?
@endolith Unplugging during write is never good. If you unplug after writing, the USB drives are all individually OK, no problem. You can unplug a drive, plug it into PC2, use it, plug it back into PC1 and remount to continue using them as before. In between the mount point on your usual PC1 needs to be informed that you took the drive (remount). But, assume you share 2 files with PC2, you can't tell which drive of the mhddfs mount they'll end up in, or if it is even the same drive. Drives are still reachable individually to check/ensure the location, but that doesn't involve mhddfs anymore.

@endolith A mhddfs on a removable disk would mean not knowing what will end on it, a unionfs makes actual sense, but requires remounting differently, depending on the availability of the removable device.

comment ipmitool pef temperature soft shutdown
Too bad IPMI-cards don't have options cheap desktop motherboards have. While I don't like the answer, since I've hoped for a better way - it is absolutely correct and my only option - accept.

If you want to avoid the redundancy of a raid, a large media and can live with single disk failures, this might work for you: serverfault.com/a/543684/165065
