HomerJ Posted May 24 Share Posted May 24 Hi all I'm in version 6.12.0-rc6 and plugins etc are updated. I've just noticed that my 3 cache drives which are formatted btrfs are unmountable and unRAID is telling me to format, but I have stuff on them. Is this because with all the recent updates I need to select something so the btrfs drives are recognised? I don't really know what to do next coz all was working fine a couple days ago and it's only changed due to the updates. Any help will be much appreciated. Quote Link to comment

Solution JorgeB Posted May 25 Solution Share Posted May 25 Try this, if the log tree is the only problem it may help: btrfs rescue zero-log /dev/nvme1n1p1 1 Quote Link to comment

Thanks for your help! If you get a spare moment, would you be able to explain how you found the problem? Should I change the btrfs file system to something else? Quote Link to comment
JorgeB Posted May 26 Share Posted May 26 The log shows that the log tree failed be read. 6 hours ago, HomerJ said: Should I change the btrfs file system to something else? Usually something else causes this issue, not directly btrfs related, but you can try a different fs if you prefer, also note that this issue tends to re-occur, if it does would recommend re-formatting the fs. 1 Quote Link to comment

Thank you so much for your help! If I change file systems, which do you think I should choose? NB it's cache. Quote Link to comment
JorgeB Posted May 27 Share Posted May 27 I assume current pool is raid1 with the 3 devices? Quote Link to comment

JorgeB Posted May 28 Share Posted May 28 For multi device pools you can use btrfs or zfs, so you could change to zfs, but note that there's no 3 device raid1 option with zfs, you can have 2 or 4 devices in raid1, with 3 devices you can only make a 3-way mirror. Quote Link to comment
