Hi to all.
I have a 5.2 production server that i would like to upgrade to the latest version.
Can I directly upgrade from the web interface ? Any additional steps? Should I upgrade to each version step-by-step or straight to the latest one ?
I have to reduce downtime as much as possible. Just...
I don't need a performance boost, this server is SSD only and it's already fast, so no need to run send/receive, right ?
Are you saying to add a new vdev to the existing pool ? Or should I create a brand new pool with it's RAIDZ-2 vdev ?
Hi to all
Current env: PVE 5.2-2 with 4 SSDs in RAIDZ-2
I would like to increase the available space by adding 4 disks more.
What do you suggest ? Creating a new standalone RAIDZ-2 pool or grow the existing one to a new RAIDZ2 ?
Is this something I can do from the web interface ? If not, as...
Using the root pool is a bad practice and you can set that as no mount (-O canmount=off)
Having it mounted to /rpool could lead to some bad practise
In example if you want to send rpool somewhere, you can't do it safely because receiving a full filesystem stream destroys the one already in...
As far as I know, using the "root pool" is a very bad practise and I see that proxmox is mounting that:
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
rpool 480G 353G 140K /rpool
is it safe to unmount ? Why are you mounting that ?
It's a shame that PVE is still requiring a dedicated USB drive and can't be placed on the same USB driver with tons of other ISO images.
it's a known 18 months bug. I've also seen a bugzilla about this.
If your VMs are PV, yes, you have to install grub (if not already present) beacuse PV VMs doesn't have a bootloader (boot process is done directly with PyGrub from the Xen host)
Usually, all debian VM still have a proper bootloaded loaded and I don't have to install anything (except virtio...
Using 4x2TB disks in a RAID10 is not an issue, but I really hate any 2-way mirror (and a RAID10 has 2 2way mirrors inside).
I had multiple full data-loss when using mirror, now all my server are on RAID-6 or at least 3way mirrors. That's why i've talked about 3way mirror
My use case are web hosting VMs. There is almost 0 sequential write like in any web hosting VM.
More or less, I have to migrate 4-5 VM, with about 400-500 sites each, that's why an L2ARC could be usefull, where ZFS will store most read files from the VM. (if ZFS is able to cache VM blocks when...
