miccos Posted March 1, 2019 Share Posted March 1, 2019 (edited) Hi, Had a quick search and couldn't find anything, but i am currently in the process of the parity swap procedure (https://wiki.unraid.net/The_parity_swap_procedure) I am at step 4 and my array is just not stopping. It is displaying 'Retry unmounting disk shares(s)' at the bottom and has been so for the last 15 minutes. I can't get see the log as it just sits waiting for tower. Is it safe for me to just power down and proceed? The help is appreciated Cheers, Michael Edited March 1, 2019 by miccos solved Quote Link to comment
miccos Posted March 1, 2019 Author Share Posted March 1, 2019 Oh i am on version 6.6.6 also Quote Link to comment
itimpi Posted March 1, 2019 Share Posted March 1, 2019 Do you have any console sessions open where the current directory is on the array? If so this will stop the disks unmounting correctly. Quote Link to comment
miccos Posted March 1, 2019 Author Share Posted March 1, 2019 No console sessions open. Not being used apart from me watching the main screen Quote Link to comment
miccos Posted March 1, 2019 Author Share Posted March 1, 2019 managed to get this: (repeated over and over) Mar 1 19:43:37 Tower root: umount: /mnt/cache: target is busy.

miccos Posted March 1, 2019 Author Share Posted March 1, 2019 only dockers use the cache and since the array is 'stopping' the dockers aren't showing as running. Quote Link to comment
miccos Posted March 1, 2019 Author Share Posted March 1, 2019 Mar 1 18:41:20 Tower nginx: 2019/03/01 18:41:20 [error] 1808#1808: *3949889 upstream timed out (110: Connection timed out) while reading upstream, client: MYPCIP, server: , request: "POST /update.htm HTTP/1.1", upstream: "http://unix:/var/run/emhttpd.socket:/update.htm", host: "tower", referrer: "http://tower/Main" if this sheds anymore light?

miccos Posted March 1, 2019 Author Share Posted March 1, 2019 Ok so I just ended up powering down. In the end I needed to disable docker in order for it to release the hold on the cache drive. Copying files from old to new parity now. Hopefully no more hiccups. Thanks Quote Link to comment

Parity doesn't have any files on it. I suspect it's copying the entire drive bit for bit from the old parity drive to the new one. Pedantic? Yes. But in IT, sometimes accurately stating what is happening prevents bad misunderstandings and possible data loss. Quote Link to comment

Some users have even thought they needed to use parity swap when they didn't really. For anybody that might be confused, parity swap allows you to replace a disabled or failing data disk with the existing parity disk and then use a larger disk in the parity slot. It is not needed any other time. Parity swap was invented so people could use a disk larger than current parity when a data disk needs replacement. The larger disk becomes the new parity, the old parity becomes the replacement data disk. Quote Link to comment
