Hello Dennis,
thank you for the installation hint. Next step is creating RAID with
hardisk. I also want to have / with /var on disk and only /boot on
SD-Card.
What is your setup?
My QNAP-NAS is
[~] # cat /proc/mdstat
Personalities : [raid1] [linear] [raid0] [raid10] [raid6] [raid5]
[raid4]
md0 : active raid5 sda3[0] sdd3[3] sdc3[2] sdb3[1]
8786092608 blocks super 1.0 level 5, 64k chunk,
algorithm 2 [4/4] [UUUU]
md4 : active raid1 sdd2[4](S) sdc2[3](S) sdb2[2] sda2[0]
530128 blocks super 1.0 [2/2] [UU]
md13 : active raid1 sda4[0] sdc4[3] sdd4[2] sdb4[1]
458880 blocks [4/4] [UUUU]
bitmap: 2/57 pages [8KB], 4KB chunk
md9 : active raid1 sda1[0] sdd1[3] sdc1[2] sdb1[1]
530048 blocks [4/4] [UUUU]
bitmap: 1/65 pages [4KB], 4KB chunk
unused devices: <none>
[~] #
I think I create
/dev/md0 = RAID 1 for OS /
/dev/md1 = RAID 1 for OS /var
/dev/md2 = RAID 5 big filesystem
First test with 4 disk with 1 TB
I will test if this work.
I have the 4 drives in a raid10
# cat /proc/mdstat
Personalities : [raid10]
md127 : active raid10 sdc[2] sdd[4] sdb[1] sda[0]
7813771264 blocks super 1.2 2048K chunks 2 near-copies [4/4]
[UUUU]
bitmap: 1/59 pages [4KB], 65536KB chunk
unused devices: <none>
I then used lvm on top of the raid array I have a data mount root and
swap
# lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log
Cpy%Sync Convert
nfs storvg -wi-ao--
-- 4.88t
root storvg -wi-ao----
50.00g
swap storvg -wi-ao---- 4.00g
I have left some space available to be allocated
# vgs
VG #PV #LV #SN Attr VSize VFree
storvg 1 3 0 wz--n- <7.28t 2.34t
