HI there,
We have a 3 server ESX3.5 Cluster backed up by a HP StorageWorks MVA F-SCSI SAN.
A LUN has been mounted as /dev/sdb, originally sitting at 500Gb. We have since extended this LUN to 1Tb, however can't work out how to get ESX to use this extra space...
If i run fdisk -l, it gives
Disk /dev/sdb: 1099.5 GB, 1099511627776 bytes
255 heads, 63 sectors/track, 133674 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 65270 524281211 fb Unknown
This shows that it sees the extra space, but cant use it. I found kittara's thread here, however when i follow the instructions through,ESX mounts it as a completey seperate datastore...
The other thing i've looked at is under Datastore properties, there is an "Add EXtent" button. I clicked that, and selected the additional space on the lun, however there's a warning there:
The Current Disk layout will be destroyed. All file systems and data will be permanently lost.
Is this true? Will it completely delete all VM data currently on that LUN?
Is there anyway i can extend the existing datastore???
Any info appreicated.
cheers
Gavin
