Hi all, I wanted to upgrade my system to amd64 and used that opportunity to install 2 240GB (1GB = 1000MB etc. unfortunately) SSDs on my rig.
The partition map is below: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 223.6G 0 disk ├─sda1 8:1 0 186M 0 part /boot ├─sda2 8:2 0 1K 0 part └─sda5 8:5 0 223.4G 0 part ├─gp01-root (dm-0) 254:0 0 1.9G 0 lvm / ├─gp01-swap (dm-1) 254:1 0 1.9G 0 lvm [SWAP] ├─gp01-usr (dm-10) 254:10 0 23.9G 0 lvm /usr ├─gp01-tmp (dm-11) 254:11 0 4.8G 0 lvm /tmp ├─gp01-var (dm-12) 254:12 0 4.8G 0 lvm /var └─gp01-home (dm-13) 254:13 0 186.2G 0 lvm /home sdb 8:32 0 223.6G 0 disk └─sdb1 8:33 0 223.6G 0 part └─gp02-virtual (dm-2) 254:2 0 143.1G 0 lvm /virtual so there are two LVM volume groups with the first one on sda hosting the OS and second on sdb using 1 partition for my VMs. I have done the following for optimization (ref: https://wiki.debian.org/SSDOptimization?action=show&redirect=SSDoptimization): 1) Kernel: Linux localhost 3.14-1-amd64 #1 SMP Debian 3.14.9-1 (2014-06-30) x86_64 GNU/Linux 2) Updated the firmware for the Intel 530 240GB disk 3) I have not gone into partition alignment for two reasons: 1) the article on debian wiki refers to is from a long time ago, 2) blockdev doesn't indicate misalignment (see below): $> sudo blockdev --getalignoff /dev/sda1 0 $> sudo blockdev --getalignoff /dev/sda2 0 $> sudo blockdev --getalignoff /dev/sda5 0 4) For mounting file systems, I have added discard in /etc/fstab and also enabled issue_discards in lvm.conf 5) Enabled deadline scheduler using udev rules as I intend to have two HDDs reconnected. 6) Added vm.swappiness as kernel option in /etc/sysctl.d/local.conf What I want to know at this point is: Is there anything else that is recommended? The section on RAMDISK options on tmpfs, does that help? Lastly, the partition alignment discussion on http://tytso.livejournal.com/2009/02/20/ is from 2009 - is it relevant today? Are any of the above "modifications" really necessary? Thanks, Kamal -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
