The trouble with this is, that tommorow another mirror might be faster. Imho right now there is no benefit in not using the default except you happen to be in a network (e.G. your university/company/ISP) who has it's own mirror. -
IIRC, Proxmox waits for the writes to actually be written to the drive (fsync, flush, that kind of thing), when it's between progress 100% and total bytes. Sounds like half of the data is still in memory if that takes as long as getting to a...

7.3 and 7.4 ISO's did not work. I had to use 7.2. I found a copy on my nas with the SHA256 hash. Installed last night.

UdoB replied to the thread Dell R730 UEFI boot installation issues.That looks weird to me; glad you found a solution.

Like.
Why does any of this matter? does your use case require a specific throughput or is it just a matter of "thats what the specs say, so should the benchmarks!" You cannot overstate this. a fast disk subsystem that can fail and take your data with... -

But then he looses the other ZFS features: https://forum.proxmox.com/threads/fabu-this-is-just-a-small-setup-with-limited-resources-and-only-a-few-disks-should-i-use-zfs-at-all.160037/

A Google search seems to indicate that this mini PC uses a NIC that is not yet supported in Linux (the Motorcomm YT6801 Gigabit Ethernet Controller). I could not confirm that from the manufacturer's web site, but saw that in a forum. If that's...

UdoB reacted to leesteken's post in the thread HELP !! Recovering ZFS disk header after running sgdisk -Z on one RAIDZ disk with Like.
A 3 drive RAIDz1 can lose one drive without losing data. What would you do then one drive broke and you needed to replace it? I suggest doing that and "replace the drive with itself" so to speak. EDIT: See also...

UdoB replied to the thread Proxmox newbie: Migration from ESXi.No, sorry. Some search engines support to filter for (for example) "M.2 with PLP", e.g. this German one...

There are not that many available in 2280 format. Kingston DC2000B Micron 7450 (Pro / Max) The Micron NVMe SSD's have higher TBW Be aware the second M.2 Slot of your Mainboard is way slower, if you use them in a mirror the second one will slow...

Du machst einen Fork von Proxmox und konfigurierst eigene Timeouts. Aber 1ms wird niemals gehen. Wenn du so etwas brauchst, musst du VMware vSphere kaufen, da hast du Fault Tollerance, mit wenigen ms Umschaltzeit. Sogar im Enterprise Umfeld...

UdoB reacted to MarkusKo's post in the thread Cluster with dual 1/10Gb network, interface priority wrong with Like.
Use a different subnet and bridge like 192.168.76.0/24 for the 10G nic's and in the datacenter options change the migration network to this network.

UdoB reacted to leesteken's post in the thread Use Cases for 3-Way ZFS Mirror for VM/LXC Storage vs. 2-Way Mirror? with Like.
I use 3-way mirrors for my backups (PBS). If it were a 2-way mirror then my data would be at risk of losing everything as soon as one side of the mirror fails. I use a 2-way mirror for everything else to prevent interruption of service when one...

Hi, In our enterprise the use case for snapshots is to restore a VM if an update failed, otherwise we only use backup with a PBS. Further explanation : Like @UdoB said snapshot is faster than backup (even with RAM included)., so before an...
-
UdoB replied to the thread Proxmox newbie: Migration from ESXi.No, that's the wrong workaround for a well known symptom. The correct (and possibly more expensive) solution is to use "Enterprise Class, with PLP" devices for ZFS. (And probably for all CoW filesystems.) PLP will give you two things: endurance...

UdoB reacted to floh8's post in the thread [TUTORIAL] PVE (rootfs) with autosnapshot, boot into snapshot and easy rollback on ZFS Raid1 for Bios or UEFI with Like.
Occasion: Actually, my one wanne build such a boot environment on BTRFS Raid1 because of my experience with timeshift in the desktop field, but while my experimentation the question comes up, of course, is this possible with zfs. And when one...

UdoB replied to the thread Feature request: Automated snapshots.While I am basically with you, for me there are some reasons: snapshots are technically cheap, very cheap snapshots are quick, the are created basically instantaneous (on disk level, without RAM) snapshots are created locally - no LAN traffic...

I do this with frequent backups (that are automatically deduplicated and which are regularly copied to other off-site systems using Proxmox Backup Server). Why do you want to want to use snapshots instead of backups (which support file-based...

UdoB replied to the thread Feature request: Automated snapshots.Yes! Meanwhile there are several external scripts helping to do so. Search for "cv4pve-autosnap" which is my personal favorite. PS: bugs and feature requests may also be placed at https://bugzilla.proxmox.com/

UdoB replied to the thread Dell R730 UEFI boot installation issues.If that one was usable successfully then 7.4 shall do too, right? Look at https://enterprise.proxmox.com/iso/ - accessible without subscription. But honestly... Debian Trixie = PVE 9 should be installable on that Dell machine!
