Hi together,
a couple of days ago I had a drive fail. No big deal I thought; That thing is still in warranty.
So I went ahead and pulled the drive in order to RMA it.
I might have made a mistake here and did not stop the arrays beforehand. The server is a Primergy RX300, so pulling the drive from the hot-swappable enclosure should have been fine. At least I thought so.
Once the replacement drive finally returned (fast forward like 3 weeks... Mistake number two incoming) I went ahead and pre-cleared it. In the meantime I was still using the array like normal and had quite a few big writes to it.
After pre-clearing was done, I stopped the array, assigned the drive and started it again to start the rebuild process. This all went without any hiccups.
The notification showed something like:
GLaDOS: Notice [GLADOS] - Parity sync / Data rebuild started
Unraid Parity sync / Data rebuild
Size: 2 TB
GLaDOS: Notice [GLADOS] - Disk 4 returned to normal operation
Unraid Disk 4 message
ST2000VN004-2E4164_Z52CCYFX (sdi)
But when I checked to see what the status is in the webUI, I found the disk to be to be unmountable. (Maybe the notification messages here are a little misleading?)
Well, I went ahead and stopped and started the array once more in the hopes of fixing the issue, but to no avail.
I also went and checked the FS with
xfs_repair -n
in Maintenance Mode in order to see what might be the issue. The log of that is attached too.
I am not all too scared about data-loss since I have backups, but am a little puzzled as to what caused this issue and how to most elegantly fix it. The data in the "Media" folder referenced in the xfs_repair log is not backed up, but can easily be re-downloaded. Most of it is *arr stuff anyway.
I was going to follow along this guide here Checking a File System, but figured it wouldn't hurt to ask before taking any actions that might not be undone.
Any advice as to how to fix and how to prevent this scenario is very welcomed and thanks in advance!
