April 28, 20224 yr After booting my server after installing some new fans, two of my drives (one parity and one data) are disabled. I tried following this guide to check and repair the data drive, but after restarting the array, the data drive is still offline. I've included the results of the most recent check/repair below: Phase 1 - find and verify superblock... Phase 2 - using internal log - zero log... - scan filesystem freespace and inode maps... - found root inode chunk Phase 3 - for each AG... - scan and clear agi unlinked lists... - process known inodes and perform inode discovery... - agno = 0 - agno = 1 - agno = 2 - agno = 3 - agno = 4 - agno = 5 - agno = 6 - agno = 7 - agno = 8 - agno = 9 - agno = 10 - process newly discovered inodes... Phase 4 - check for duplicate blocks... - setting up duplicate extent list... - check for inodes claiming duplicate blocks... - agno = 1 - agno = 0 - agno = 2 - agno = 3 - agno = 4 - agno = 5 - agno = 6 - agno = 7 - agno = 8 - agno = 9 - agno = 10 Phase 5 - rebuild AG headers and trees... - reset superblock... Phase 6 - check inode connectivity... - resetting contents of realtime bitmap and summary inodes - traversing filesystem ... - traversal finished ... - moving disconnected inodes to lost+found ... Phase 7 - verify and correct link counts... done I've also attached my diagnostics export. I have a spare drive that I can install if needed, but the timing and the fact that two of them went out at the same time to me suggests that it isn't a hardware issue. I did try reseating all of the drives as well. Any insight or ideas are much appreciated! lof1-nas-diagnostics-20220428-0059.zip Edited April 28, 20224 yr by LOF_HWalker changing title since issue was solved

LSI is using the MegaRAID driver, that's not recommended, see if it can be flashed to IT mode.
April 28, 20224 yr Author Ahhhhhh ok that makes sense. The parity sync/data rebuild is running now, so we'll see if I have any further issues from there. 7 minutes ago, JorgeB said: P.S.

April 28, 20224 yr That's RAID only, no IT mode, it's not recommended, doesn't mean it won't work, if you get more issues make sure you grab the diags before rebooting.
April 28, 20224 yr Author Yeah when we originally specced this system it was going to run Windows so they used a RAID card. We've been using this for over a year without issue, so hopefully this is just a one-time issue, but I'll make sure to grab diags before rebooting if we run into anything else.
