Finally got my MD RAID5 configured and its awesome
Posted: Tue Dec 20, 2011 7:28 pm
So I have had a bit of an interesting journey with my HDA - I am now on my third rebuild due to DNS and other issues. Last night I got my MDADM RAID5 configured and synced up (3 x 2TB WD20EARS 5.9K drives). The initial RAID sync took under 5 hours which is quite good for any RAID array - even high end stuff like the Dell Equallogic and EMC Clariion gear that I work on for my day job, let alone a cheapo, low voltage Linux NAS.
I was able to get some baseline performance figures this morning copying files over a gigabit ethernet link from an OCZ Agility SSD to minimise the bottleneck on the client side and I am able to get around 100+MB/s! (with standard MTU size and no other optimisations) which is quite impressive indeed for a software RAID and probably a limitation of the crap Dlink gigabit ethernet switch I am using.
I have played around with large ZFS implementations but this is quite cool - Having said that I am yet to see how the long term reliability goes.
How is everyone seeing the long term stability of MDADM running with Amahi?
