Meta-data area 256 MB so no problem there. I just upgraded linux kernel+headers+etc to 18.104.22.168-64 (fc11.x86_64) and recompiled DRBD 8.3.4 from scratch to this kernel. Completely zeroed out external meta-data partition, then reran 'drbdadm create-md' command. Started DRBD service. Running 'cat /proc/partitions' shows the following sizes : 5807677440 dm-0 (logical backing volume for DRBD) 4293787648 drbd0 As usual, when mounting drbd0 I receive the same error message about invalid superblock, and 1 line in /var/log/messages is logged: kernel: EXT4-fs: bad geometry: block count 1451919360 exceeds size of device (1073446912 blocks) What could cause the discrepancy between the logical and DRBD volume sizes ? -- View this message in context: http://www.nabble.com/Error-when-trying-to-mount-drbd-partition-%3A-%27Bad-geometry%3A-block-count-xxx-exceeds-size-of-device%27-tp25779479p25795874.html Sent from the DRBD - User mailing list archive at Nabble.com.
