OK, after spending a lot of time googling softraid 5 info, I'm still
uninformed. A lot of the info is either contradictory or assumes that
you're using gui tools. I did all of this a few years ago on this same
box using fedora 7 and 4 500gig disks. I obviously didn't retain the
recipe I worked up back then.
So: the questions I need answered:
1). What is the correct way to partition the 4 physical disks: fdisk?
gdisk?
2). What is the correct partition type to select? fd00?
3). Once the drives are partitioned, do they need a file system on
them..i.e. do they need to be formatted before using mdadm --create?
If yes, why? And if yes, which filesystem?
4). Once the disks are prepared and mdadm start to create the device,
is it reasonable to expect that mdadm will take up to 20 hours? This
is what mdstat is telling me:
Code:
--------------------
cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4]
[raid10]
md0 : active raid5 sde1[4] sdd1[2] sdc1[1] sdb1[0]
5860543296 blocks level 5, 64k chunk, algorithm 2 [4/3] [UUU_]
[>....................] recovery = 0.7% (15141256/1953514432)
finish=1128.7min speed=28620K/sec
--------------------
5). After mdadm --create has finished, again, what is the best
filesystem to put on the /dev/md0 device for my purposes. ext4, as
SuperQ suggests above?
