Hello List, i have a rbd block device with xfs on it. After resizing it (from 6TB to 8TB i think) the mount need hours to complete: I started the mount 15mins ago.: mount -nv /dev/rbd6 /mnt/backup-cluster5 ps: root 1143 0.2 0.0 8904 3088 pts/0 D+ 12:17 0:03 | \_ mount -nv /dev/rbd6 /mnt/backup-cluster5 There is no timeout or ANY msg in dmesg until now. strace -p 1143 : seems to do nothing. iotop --pid=1143: uses about 50KB/sec dd bs=1M count=2048 if=/dev/rbd6 of=/dev/null => gives me 50MB/sec Any idea what´s the problem here? Cheers, Michael
