IMO it is best to make that not matter. If you're referencing drives by letter in configuration files, you're just asking for some change to re-order things and cause problems. You're using LVM, so all the drives should be assembled based on their embedded metadata. It is fine to reference whatever temporary device name you're using when running pvmove/pvcreate since that doesn't really get stored anywhere. If you are directly mounting anything without using LVM then it is best to use labels/uuids/etc to identify partitions. > It also triggered > messages from SMART too. It got upset that it couldn't find sdd anymore. That is typical when hotswapping. I believe smartd only scans drives at startup, and of course if a drive does go offline it isn't a bad thing that it is noisy about it. From a quick read of the manpage SIGHUP might or might not get it to rescan the drives, and if not you can just restart it. The daemon works by polling so if there are any pending issues they should still get picked up after restarting the daemon. -- Rich
