Hi all,
I'm revisiting this topic after a few years - so excuse me if I'm a
little behind the times on this questioning.
I'm just starting to replace some 5 year old disks in a RAID6 (5 disks)
due to one having started to throw uncorrectable / reallocated sectors.
As such, it seems a good time to go to 3Tb drives - which are only $20
more than 2Tb drives.
The array is created as follows:
md2 : active raid6 sdf[0] sde[6] sdg[7] sdd[5] sdc[8]
5860150272 blocks super 1.2 level 6, 128k chunk, algorithm 2 [5/5]
[UUUUU]
I've always used the whole disk for the RAID6 - as from what I
understand, this gives the best layout for various drives - no matter if
they're 512 or 4096 byte sectors.
Is this still the case?
I've noticed that my resync speeds on this RAID6 hover around 60Mb/sec -
which I was expecting to be a bit quicker (although I haven't tested
speeds on this array for years).
Currently using kernel 4.1.15 on an EL6 install.
Would be grateful for any input people may have on these topics.
