Oren,
AFAIK, DRBD doesnt support snapshotting natively. Therefore, if Im correct, you only have 2 ways to achieve what you intend to do : - Setup an VG/LV structure on top of your DRBD resource and make use of the LVM snapshot facility. Beware, Ive read many articles mentioning that write performances were dropping down severely in that case. Dont know if its still the case Google a bit to check that point. - Use snapshot features of your storage array, providing it is able to do so Best regards, Pascal.

Namely, on each (e.g., of the two) nodes Allocate space in advance Configure DRBD to /dev/drbd0 /dev/sda1 - active partition /dev/sda0 - dedicated for keeping one snapshot Take snapshot should be fast - much faster than dd Allow Reverting to the snapshot Also, are there other means to achieve this, apart from buying storage? Thanks in advance, Oren
