Ještě si s tím hraju přepnul jsem zpátky na Legacy a zapnul cache. Rychlosti plus mínus stejné. Nicméně queue_depth=1, když chci zapsat hodnotu 32 napíše mi to:
Kód: [Vybrat]
root@pve:~# echo 32 > /sys/block/sda/device/queue_depth
-bash: /sys/block/sda/device/queue_depth: Permission denied
Kód: [Vybrat]
root@pve:~# hdparm -W /dev/sd[abcd]
/dev/sda:
write-caching = 1 (on)
/dev/sdb:
write-caching = 1 (on)
/dev/sdc:
write-caching = 1 (on)
/dev/sdd:
write-caching = 1 (on)
