Hello list, |
| 2 |
|
| 3 |
A week ago the 2.5" drive on my Atom LAN mini-server failed, so I decided to |
| 4 |
bite the bullet and replace it with an SSD. Interesting times! |
| 5 |
|
| 6 |
Today I took the box off-line and backed up the entire, newly built system to |
| 7 |
external USB2 disk. The 3GB took four minutes, a third or a quarter of the |
| 8 |
previous time on the spinning disk. Good news! |
| 9 |
|
| 10 |
I find though that fstrim can't operate on /boot, which is a separate ext2 file |
| 11 |
system. It reports: |
| 12 |
fstrim: /boot: FITRIM ioctl failed: Inappropriate ioctl for device |
| 13 |
Is this because it's an ext2 partition, not ext4 like the rest of them? Man |
| 14 |
fstrim makes no mention of file-system types. |
| 15 |
|
| 16 |
Maybe I've not laid out the partitions properly. I used gparted from a recent |
| 17 |
System Rescue CD (http://sysresccd.org), which said it was leaving 1MB unused |
| 18 |
before /dev/sda1. |
| 19 |
|
| 20 |
While I'm here, would anyone like to suggest suitable parameters to mkfs for |
| 21 |
any of my file-systems? Here's the fstab: |
| 22 |
|
| 23 |
/dev/sda1 /boot ext2 noauto,relatime 1 2 |
| 24 |
/dev/sda2 none swap sw 0 0 |
| 25 |
/dev/sda5 / ext4 relatime 0 1 |
| 26 |
/dev/sda6 /var ext4 relatime 0 2 |
| 27 |
/dev/sda7 /home ext4 relatime 0 2 |
| 28 |
/dev/sda8 /var/cache/squid ext4 relatime 0 3 |
| 29 |
/dev/sda9 /usr/portage ext4 relatime 0 3 |
| 30 |
/dev/sda10 /usr/portage/packages ext4 relatime 0 4 |
| 31 |
/dev/sda11 /usr/local ext4 relatime 0 2 |
| 32 |
proc /proc proc defaults 0 0 |
| 33 |
tmpfs /tmp tmpfs nodev,nosuid 0 0 |
| 34 |
tmpfs /var/tmp tmpfs nodev,nosuid 0 0 |
| 35 |
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0 |
| 36 |
|
| 37 |
I created all the ext4 file-systems with -O ^has_journal to avoid concentrated |
| 38 |
wear. Is this still a good idea nowadays? I'm happy to sacrifice the comfort of |
| 39 |
journalling since recovering this small box from backup is so quick and easy. |
| 40 |
Of course I did plenty of googling before doing anything and picked out what |
| 41 |
still seemed appropriate, but I could easily have missed something important. |
| 42 |
