Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.
Please confirm that on both machines, when each is primary, you have mounted:
mount /dev/drbd0 /drbd
and not
mount /dev/sdb1 /drbd

Subject: [DRBD-user] proto c - corrupt files - directories missing
Dear Users,
we're using drbd version 2:8.3.11-3~bpo60+1 with Kernel 3.2.46-1~bpo60+1 on debian 6.0.7 amd64.
drbd always shows clean status:
root at zabbix-linux-N1:/# cat /proc/drbd
version: 8.3.11 (api:88/proto:86-96)

I have an ext4 filesystem on top of drbd0. I can mount the FS on the active node without problems.
Only if node N2 becomes the active one (primary), some of the files are garbage and some folders are missing.
File /drbd/index.php tells me data instead of PHP script test.
Furthermore on N1 I have /drbd/testfolder/
On N2 this folder is not synced.
I also enabled data-integrity-alg but no errors were logged.
Any ideas?!
Thank you
Stefan
