I have had some odd issues and I want to make sure i am not losing Data. I have 6 disk plus parity. 1 6tb parity drive, 2 6tb drives and 4 3tb drives. So 24TB total with 9tb free.
I had one 3TB drive that starting errors so I removed it and rebuilt the parity. Everything seemed to go well. Now I now have another 3TB drive that is randomly showing up as Unmountable: No File System. I was able to get to finally get it to come up and mount doing a xfs_repair but after reboot its tends to go back to the Unmountable: No File System state.
Here is my question. If I am able to get it to report in and mount after doing another xfs_repair can i do a parity check and then remove the drive as well? I have a replacement on the way but do not want to lose what's on it. If the parity is good and the drive is mounted can I remove it and add a new and let it rebuild with out concern?
