Re: BTRFS converted from EXT4 becomes read-only after reboot

My setup is a single disk, single btrfs subvolume (/) without a separate boot partition. I resolved the issue like this from a Live CD: 1 - take a (read-only) snapshot of the current problematic root system and use send-receive to another BTRFS disk 2 - re-format the original partition as btrfs

Getting a bit off-topic here, but were you able to boot from that fs with grub after a simple rsync? On Mon, May 8, 2017 at 1:01 PM, Sean Greenslade wrote: > On Mon, May 08, 2017 at 12:41:11PM -0400, Austin S. Hemmelgarn wrote: >> Send/receive is not likely to transfer

Re: BTRFS converted from EXT4 becomes read-only after reboot

Deleting the Firefox cache with the LiveCD resolved the issue where the FS would become read-only when opening Firefox, however, the lowmem check still reports errors. There are probably some other files that would cause the FS to become read-only again, but I'm not sure how to find them. I took a

BTRFS converted from EXT4 becomes read-only after reboot

Hi all, In a VirtualBox VM, I converted a EXT4 fs to BTRFS that is now running on Ubuntu 16.04 (Kernel 4.4.0-72). I was able to use the system for several weeks. I even did kernel updates, compression, deduplication without issues. Since today, a little while after booting (usually when I start
