I just got a new server with a Dell MD-1000 SAS unit and 6-750 gigabyte drives which are now initializing in RAID 10 which will give me just about 2 terabytes.
I vaguely recall reading that fdisk wasn't suitable for partitioning and wonder if I shouldn't be using partd instead. I am also wondering if I should use lvm or just mkfs to create the filesystem. Anyone have suggestions before I blunder in?
Just pvcreate the whole disk and forgo partitioning it. Then create a vg out of it and start creating lvs.
---- OK - makes sense but I am a bit confused here.
I have done the pgcreate and tested lvcreate but wonder about 'setphysicalextentsize' because in the man page, it states, "The default of 4 MB leads to a maximum logical volume size of around 256GB" which makes me think that if I want one volume when this is all done, I have to increase that value.
# fdisk -l /dev/sdb
Disk /dev/sdb: 2248.8 GB, 2248818032640 bytes 255 heads, 63 sectors/track, 273403 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdb doesn't contain a valid partition table
So thinking that I would need a volume just under 10 times the maximum of 256GB, I would have to set the physicalextentsize to 64 MB (32 not being quite large enough and thus 64 being the next increment in power of 2)
Does this make sense?
