CentOS 6.6 SSD trim on HP DL380 G2 RAID 0
I'm running glusterfs on CentOS 6.6 two nodes, (the SSD (samsung 840 1TB x2) is RAID 0 on the HP DL380 G6) x2, and trimming is not enable on it by checking /dev/sdb1/xxxxx/discard_max_bytes=0. Do I still need trimming? Somehow my filesystem is fine with 35-30% free space and running very fast.
Thanks for any comment you may add.

Nowadays the fastest SSDs achieve read-speeds of between 1500 MB/s to 1900 MB/s. Let's say that two such SSDs in RAID 0 achieve roughly double the throughput, ie 3000 MB/s. That is only half an order of magnitude removed from RAM ((10)^(1/2) * 3000 = 10.000), very broadly speaking.
So for the... (6 Replies)

raidfile.conf
RAIDFILE.CONF(5) Box Backup RAIDFILE.CONF(5)
NAME
raidfile.conf - Userland RAID for Box Backup
SYNOPSIS
/etc/box/raidfile.conf
DESCRIPTION
The raidfile.conf is usually generated by raidfile-config(8) but may be manually edited if the store locations move or if more than one
disc set is required.
discX
Specifies a set of discs.
SetNumber
The set number of the RAID disc, referenced by each account.
BlockSize
The block size of the file system (usually 2048). Under BSD with FFS, set this to your file system's fragment size (most likely an
8th of the block size).
Dir0
The first directory in the RAID array.
Dir1
The second directory in the RAID array. If you do not wish to use the built-in RAID functionality, this field should be set to the
same as Dir0. You should not use the built-in RAID if you have a hardware RAID solution or if you're using another type of software
RAID (like md on Linux).
Dir2
The third directory in the RAID array. The same notes that apply to Dir2 also apply to Dir3.
