A Dell R610 server with LSI 9207-8i HBA card has 6 Samsung 850 PRO SSDs connected to it.
hdparm
shows TRIM support:
sudo hdparm -I /dev/sdc | grep -i trim
* Data Set Management TRIM supported (limit 8 blocks)
However executing the Samsung magician software on Ubuntu 14.04 returns the following error:
ERROR : This feature is not supported for disks connected to LSI RAID HBA Cards.
Neither does the fstrim
command help:
fstrim: /: FITRIM ioctl failed: Operation not supported
The compatibility matrix doesn't list the Samsung 850 PRO so should I get another controller that supports this SSD for TRIM to work?
I do not need any hardware RAID capabilities and intend to configure these 6 drives with RAID 10 using mdadm
.
