Dan Gravell Posted March 17, 2021 Share Posted March 17, 2021 I know - running within VirtualBox isn't supported. Feel free to ignore and I'll get the message. However, I have managed to get as far as playing about with Docker, so I was hoping someone might be able to give me a pointer. Whenever I try to install an app from Community Applications, when the docker pull starts, I eventually get errors like: Mar 17 15:55:43 Tower kernel: print_req_error: 55 callbacks suppressed Mar 17 15:55:43 Tower kernel: blk_update_request: critical space allocation error, dev loop2, sector 80064 op 0x1:(WRITE) flags 0x1800 phys_seg 43 prio class 0 Mar 17 15:55:43 Tower kernel: blk_update_request: critical space allocation error, dev loop2, sector 604352 op 0x1:(WRITE) flags 0x1800 phys_seg 43 prio class 0 Mar 17 15:55:43 Tower kernel: BTRFS: error (device loop2) in btrfs_commit_transaction:2377: errno=-5 IO failure (Error while writing out transaction) Mar 17 15:55:43 Tower kernel: BTRFS info (device loop2): forced readonly Mar 17 15:55:43 Tower kernel: BTRFS warning (device loop2): Skipping commit of aborted transaction. Mar 17 15:55:43 Tower kernel: BTRFS: error (device loop2) in cleanup_transaction:1942: errno=-5 IO failure ... and the install fails. I don't have a cache AFAIK. I have tried recreating docker.img but that hasn't fixed it. I have tried scrubbing the btrfs volume, but that didn't help. Diagnostics attached... Very grateful for any help. tower-diagnostics-20210317-1605.zip Quote Link to comment
JorgeB Posted March 17, 2021 Share Posted March 17, 2021 Docker image is on disk1, and disk1 is full: Filesystem Size Used Avail Use% Mounted on /dev/md1 2.0G 2.0G 24K 100% /mnt/disk1 1 Quote Link to comment
Dan Gravell Posted March 18, 2021 Author Share Posted March 18, 2021 Thanks - I made a stupid assumption that storage was abstracted in the same way lvm would do - I didn't think individual disks mattered. So I recreated the disks, much larger, and it works. Thanks again. 1 Quote Link to comment
