Re: [solved] [FAILED] Failed to start Remount Root and Kernel File System

For anyone looking into this after me, that error occurs in context on line 538 of that paste.  I note an informational warning from BTRFS immediately before that crash, but I have no experience using that FS yet personally, and it's only an informational note so it may not actually be a real warning with any consequence.

Thanks levi. There's also a

[    3.972114] BTRFS info (device sda2): unrecognized mount option 'space_cache.subvol=@snapsthots/TESTING'

which looks like BTRFS is missing somehow (or at least some options are not supported).

Yes, that's line 535, so the line just before the section that ends with that [FAILED] notice. That and the line before it seem to occur again five times before dmesg ends.  Are you suggesting those notes don't come from a BTRFS component?  I had assumed they were, which either means a miconfigured fstab or a misinstalled BTRFS, as I see it, but as I say I've not played with BTRFS myself so I can't be sure.

Re: [solved] [FAILED] Failed to start Remount Root and Kernel File System

Hello, i have solved the Problem, my /etc/fstab not good.


LABEL=ROOT / btrfs rw,noatime,compress=lzo,space_cache.subvol=@snapsthots/TESTING 0 0

right ----->
LABEL=ROOT / btrfs rw,noatime,compress=lzo,space_cache,subvol=@snapshots/TESTING 0 0
(Change dot and snapshots)

Thank's for your help.

Hah, that misspelling of snapshots was right there on line 353 of the log and repeated 5 times throughout, but I just didn't see it.  Might need to upgrade vgrep wink

Hello levi, you mean line 535.

535  [    3.972114] BTRFS info (device sda2): unrecognized mount option 'space_cache.subvol=@snapsthots/TESTING'

353 isn't 535.

Thank's

I do indeed.  Might need to look into refreshing my typing fingers as well wink
