Hi, i want to expand a btrfs filesystem. In the moment I have four 2 TB HDDs for one btrfs pool. I want to replace two of the HDDs with 3 TB devices. For this reason i added as first one 3 TB device. After that, i do the btrfs delete job. This job lasts since 4 days and it seems, that it hangs. Is it possible to cancel a btrfs delete job? And when so, how can i do that?
Unfortunately you can't cancel btrfs delete. Q1. Does your environment and operations are as follows? Environment: - You have six disks. - four 2TB disks: /dev/sd[a-d] - two 3TB disks: /dev/sd[ef] - Currently your btrfs filesystem consists of /dev/sd[a-d]. - You want to replace /dev/sd[cd] with /dev/[ef]. Your operation: 1. Add one 3TB disk, /dev/sde. # It works correctly. 2. Delete one 2TB disk, /dev/sdc # Hanged up happens here! Q2. Does I/Os for delete still in progress, or there is no I/O? Thanks, Satoru
