sendas Posted October 14, 2021 Share Posted October 14, 2021 I have a test machine running unraid with 1 parity drive and 1 cache drive. My parity drive died on me. Is there any way to mount and recover the data that is on the cache drive? The data on there is replaceable but theres acouple of config files I'd rather not remake. Quote Link to comment
Squid Posted October 14, 2021 Share Posted October 14, 2021 Not really following. You can't have a system composed of simply 1 parity drive and 1 cache drive. If your parity drive died, then all of the data disks are still intact along with your cache drive. Post your diagnostics Quote Link to comment
sendas Posted October 14, 2021 Author Share Posted October 14, 2021 Sorry I got confused on the drive configuration. It used to have more drives that have been pulled awhile back. The Seagate ST131500341AS is the bad drive. it makes a clicking sound and isn't detected by unraid. What Im trying to do is without the array started, mount my WD Blue cache drive /dev/sdf to /mnt/sdf and cp some files off. tower-diagnostics-20211014-1348.zip Quote Link to comment
trurl Posted October 14, 2021 Share Posted October 14, 2021 Your diagnostics show you have a missing parity drive and a disabled and missing disk1. If you put that parity drive back then you only have a disabled and missing disk1 and you can start the array without disk1. Quote Link to comment
trurl Posted October 14, 2021 Share Posted October 14, 2021 If it is the parity drive that isn't working, just don't assign any disk to parity, keep cache as assigned, and assign any other disk as disk1, then you can start the array and that will give you access to cache. 1 Quote Link to comment
sendas Posted October 14, 2021 Author Share Posted October 14, 2021 Nice! thank you. That parity drive is in use. Putting a new disk1 did the trick, was able to get that data off. Quote Link to comment
