October 24, 20178 yr Hey, I had a power failure which means i needed to do a parity check. For some reason my system crashed during the parity check a few hours in and upon restarting 3 of my 13 array drives were un-mountable. All drives corrupt were XFS. 9 drive are RFS and 4 are XFS. I'm just wondering if XFS is more volatile than RFS. I was missing around 1.5TB of data over the 3 drives after doing a xfs_repair and am now running a recovery through UFS Explorer to try and get the data back. I think its found most of it but the file structure/names are never coming back. Although this loss is devastating as i may not get everything back its my own fault for trusting parity. After recovering what i can and organise what was saved im going to backup everything thats irreplaceable offsite. I think ill also add a UPS to my setup.
