September 16, 20223 yr Hi, I shutdown my server whilst an electrician was working in the house and then rebooted to find I had a disk that won't mount. I'm hoping I don't need a new disk and haven't lost data. I've read the help and followed the process to Check the filesystem but not sure how to proceed. Any help greatly appreciated! Here's what the filesystem check shows and I've attached my diagnostics zip file Phase 1 - find and verify superblock... Phase 2 - using internal log - zero log... ALERT: The filesystem has valuable metadata changes in a log which is being ignored because the -n option was used. Expect spurious inconsistencies which may be resolved by first mounting the filesystem to replay the log. - scan filesystem freespace and inode maps... - found root inode chunk Phase 3 - for each AG... - scan (but don't 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 - process newly discovered inodes... Phase 4 - check for duplicate blocks... - setting up duplicate extent list... - check for inodes claiming duplicate blocks... - agno = 1 - agno = 2 - agno = 0 - agno = 6 - agno = 5 - agno = 4 - agno = 7 - agno = 3 No modify flag set, skipping phase 5 Phase 6 - check inode connectivity... - traversing filesystem ... - traversal finished ... - moving disconnected inodes to lost+found ... Phase 7 - verify link counts... No modify flag set, skipping filesystem flush and exiting. I have also attached Smart report for drive in question and the latest Smart Errors. Not sure if they are relevant?

September 16, 20223 yr Author mothership-diagnostics-20220916-1240.zip Thanks for the reply. Here's the latest diagnostics following roboot and array start. It's been a while since I built the machine but it's a Mini-ITX build so I'm not sure I had the luxury of multiple ports? It's been working fine for 3-4 years but I realise it might not be ideal.
September 16, 20223 yr You can use an add-on controller, just use one without port multipliers, disk itself looks OK, replace the SATA cable since there are some recent UDMA CRC errors, and since the emulated disk is mounting and assuming contents look correct you can rebuild on top: https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself
September 16, 20223 yr Author Ah brilliant. Thanks very much. I'll do what you suggest and let you know how I get on.
September 16, 20223 yr Author Just as a follow on, in replacing the controller. This is the current card that I have is PCI 2.0 https://www.amazon.co.uk/dp/B005B0A6ZS/ref=as_li_ss_tl?language=en_US&ie=UTF8&linkCode=gg2&linkId=c0893f24a38dd363c84f64c8f1f3ff32&tag=serverforums-20&th=1 Will my system be okay to get one of the recommended PCI 3.0 card? The build I have was taken from this guide and is the 6-bay Mini-ITX NAS (scroll down to see) and the pertinent information from the build was "The case has room for 6x3.5" HDD as well as 2x2.5" SSD. The motherboard has 4 onboard SATA, so we need to add either a 2 port card (for 6xHDD) or a 4 port card (for 6xHDD + 2xSSD) to take advantage of the rest of the drive bays. I recommend a MSATA SSD 833 for cache if you’re going to use Unraid. This leaves 6x3.5" for parity and data. I’d only run 1 parity drive in a 6 bay NAS like this. If you go for the 4 port card, you can have 2 more SSDs as unassigned devices. (VM storage, unpack drives, non-parity/non-crucial data, etc.)"

September 16, 20223 yr Author Hi again, I seem to have more disks unable to mount now after swapping some SATA cables out. I think I'm going to get a new controller to eliminate all possibilities. I've been going round in circles a bit but think this might do the job. I think it matches one of the recommended chipsets although it's quite a bit more expensive than my last one. What do you think? Thanks again, and apologies for my lack of technical knowledge https://www.amazon.co.uk/SATA3-0-Expansion-PCI‑E3-0-Interface-Adapter-default/dp/B097MQ6K31/ref=sr_1_4?crid=2JCG40YXTXV&keywords=Asmedia+ASM1166&qid=1663348894&sprefix=asmedia+asm1166%2Caps%2C53&sr=8-4
