Readynas Data Volume Full - Stuck booting at 99%
Hello,
My data volume /data is full and my Readynas 516 is stuck booting at 99% (Status: System starting up). Is there a way to get past this so I can free up some space? I've looked at previou...
Hi StephenB,
Thanks for the suggestion, I can list (btrfs subvolume list /data) the subvolumes, but unfortunately when trying to delete snapshots (btrfs subvolume delete /data/directoryname/.snapshots/XXX/snapshot) the command hangs.
Is df showing that the volume is full, or is it btrfs fi df?
Do you have a full backup? If not, this would be a good time to make one. You can mount a USB drive manually.
Then maybe try
btrfs balance start -v -dusage=0 /data
This will reallocate any unused blocks to free space - which could free up a bit of free space.
Hi Stephen,
Unfortunately, I can't mount the filesystem (btrfs -o ro /dev/md127 /mnt). When I try to it eventually says it can't read superblock. I am unable to mount/read the data in either normal or read-only boot mode. When I boot in normal mode it tries to mount the volume to /data and can't be unmounted at that point although I can successfully get results from "btrfs fi df -H /data" and "btrfs subvolume list /data" (after normal boot). How long does the balance usualy take. Thanks!# btrfs fi df -H /data
