Comment #16 on issue 256 by [email protected]: DRBD Volume above 4TB not
working
https://code.google.com/p/ganeti/issues/detail?id=256
Find as attachment a bash script that we use on a 2 node production server
to use DRBD disks > 4 TB.
usage: gnt-drbd-meta-disk-size get | set SIZE[MGT]
get or set ganeti DRBD meta disk size computed from DRBD disk size
- SIZE is the DRBD disk size expressed in MiB by default
- M/G/T suffixes can be used for MiB/GiB/TiB
- DRBD meta disk size < 128 MiB use the 128MiB default of ganeti
This script can be used to set temporay DRBD meta disk size for:
- instance creation using only disks > 4064 GB
- adding a disk > 4064 GB to an instance using already ganeti default
DRBD meta size that won't be relocated away from initial nodes
WARNING:
- both DRBD nodes involved need to use the same DRBD meta disk size
for disk creation/addition
- all DRBD nodes involved in DRBD instance relocation need to use
the same DRBD meta disk size
- This script can't handle instance relocation with instance using
several DRBD disk using different DRBD meta disk size
- Doesn't have been tested with backup/export
