xrqp Posted February 18, 2021 Share Posted February 18, 2021 For the unmountable disk, I ran the "Checking a File System" with -n option, and copied the report into the attached docx file. If I pasted it here, it is so many pages it seems to create problems. unmountable hard drive, check file system report .docx "Repairing a File System" instructions say: Add any additional parameters to the Options field required that are suggested from the check phase. If not sure then ask in the forum. I am not sure at all what the report means, so asking here what parameters I should set? Thanks. Quote Link to comment
JorgeB Posted February 18, 2021 Share Posted February 18, 2021 That looks like a very corrupt filesystem, but basically you can only attempt to repair it without -n, is that an emulated disk or actual disk? Quote Link to comment
xrqp Posted February 18, 2021 Author Share Posted February 18, 2021 I think it is an actual disk. How do you tell if it is emulated or actual? What parameters I should set for the repair, other than remove the -n? Quote Link to comment

Actual disk will have a green ball on main page, emulated disk yellow or red. 3 minutes ago, xrqp said: What parameters I should set for the repair, other than remove the -n? You can use -v for increased verbosity, though it doesn't make much difference. Quote Link to comment
xrqp Posted February 19, 2021 Author Share Posted February 19, 2021 it has the green ball if I spin it up, so it is actual disk. Running the check fix now with no options (no parameters) for about 10 minutes and ongoing. The help said when the check fix is running to "refresh" the monitor. I guess they are referring to the internet browser program. The help said use -L option if it tells you to. Mine did not tell me that yet. My disk is xfs. What does -L do? Quote Link to comment

xrqp Posted February 22, 2021 Author Share Posted February 22, 2021 (edited) I started the repair Feb. 18 at 5pm, now Feb 22 1am it is still repairing the 8TB drive. Is it supposed to take this long? I checked the "reads" periodically. (Help says "reads" is a count of I/O requests sent to the device I/O drivers.) Reads Date time 113k Feb 18 126k Feb 18 11:40pm 421k Feb 19 1pm 233k Feb 21 1pm (why did reads go down?) 253k Feb 22 1am why did reads go down on Feb 21. how long does it take to repair 8TB drive? Here is what my screen says at Check Filesystem Status, xfs_repair status: Phase 1 - find and verify superblock... Phase 2 - using internal log - zero log... Log inconsistent or not a log (last==0, first!=1) empty log check failed zero_log: cannot find log head/tail (xlog_find_tail=22) ERROR: The log head and/or tail cannot be discovered. Attempt to mount the filesystem to replay the log or use the -L option to destroy the log and attempt a repair. Should I stop the repair, and start it again with -L option?

Reads Repair time is normally measurable in minutes so it seems something is going wrong You are likely to get better informed feedback if you attach your systems diagnostics zip file (obtained via Tools->Diagnostics) to your NEXT post.

I thought the reads increasing was the only way to know it is running (built in help). Last night I found spaceinvaders youtube on this called How to Fix XFS File System Corruption on an Unraid Server. Now I did repair with -L. This time I watched it closer. I think it went well. Thanks for your replies. Edited February 22, 2021 by xrqp Quote Link to comment
