Hello,
I´ve installed the latest Proxmox 4.1 via iso on one of my dedicated servers. The specs are:
CPU1: Intel(R) Core(TM) i7 CPU 950 @ 3.07GHz (Cores 8)
Memory: 24061 MB
Disk /dev/sda: 750 GB (=> 698 GiB)
Disk /dev/sdb: 750 GB (=> 698 GiB)
Disk /dev/sdc: 120 GB (=> 111 GiB)
Total capacity 1509 GiB with 3 Disks
I do the installation with a ZFS-RAID1 over sda and sdb, and left sdc (the SSD disk untouched) to use later as cache (ZIL - L2ARC) and i have now the following issues/doubts:
1. In the case in the proxmox 4.1 iso install, if i choose a zRAID1 with all disk (including the SSD), i suppose that this build by default a RAID with the 3 disks BUT the SSD act as mirror not for caching, so i think proxmox will NOT configure the ssd as cache with this option, right? Or can i configure the ssd disk easy as cache in the installation?
2. For now, on my proxmox install ssd disk not appears, it is not inicialited (i can´t see it with a cfdisk /dev/sdc for example). So the next step should be inicializate disk -acording all i have reading- make 2 partitions, one for ZIL and other for L2ARC, in commandline like:
gpart destroy -F sdc // First i should debete current partitions on sd
gpart create -s GPT sdc
gpart add -s 90G -t freebsd-zfs // And here two partitions
If i am in the right direction, what size for a 120 GB ssd for each partition?
3. The next i suppose will be somethink like ¿?:
zpool add [pool] cache [drive]
4. Partitions on current sata drives
This is my current partition scheme:
Filesystem Size Used Avail Use% Mounted on
udev 10M 0 10M 0% /dev
tmpfs 2.4G 392K 2.4G 1% /run
rpool/ROOT/pve-1 661G 678M 661G 1% /
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 9.4G 0 9.4G 0% /run/shm
rpool 661G 128K 661G 1% /rpool
rpool/ROOT 661G 128K 661G 1% /rpool/ROOT
Note that only sda and sdb are in RAID1 and i have only a zpool (rpool), leaving it by default, like installation. I have checking and most people create diferent zpools, for containers/vm, space backups...for example. Should i do then some separate pools? Can anybody guide me on this too?
Thank you all in advance for all help and suggestions since i am new in proxmox world (i came from solusvm & openvz virtualization)
Best regards!
