I know this is a common issue, but I cant get it going with the typical settings. I can create on LVM, but not on zvol, nor ZFS file system. I have added a ZFS storage type on the storage page, and a directory to the dataset mount. When I try to move the drive from my lvm to the zfs dataset I...

I am having stability issues on mine, pve 5.0-23, pfsense v2.4.3, any ideas?? My main firewall died last weekend, and having a R720 with 4 nics, as a temporary fix, I loaded a pfsense VM and was online... but after a random time, sometimes a couple days, sometimes 8 hours, the WAN gateway shows...

Yes, I know it is, which assumes a reboot.... but I decided to go check this on a newer system, and it works as desired - the zdx and zvol references are both generated on the fly WITHOUT a reboot. however on the other system that was dist-updated in the last 4-5 days is not creating the zvol...

I am cloning a zvol snapshot, and the new zvol shows up properly under zfs list, but it does not populate in /dev/zvol nor zd* and my goal is the mount the zvol on the host to recover some files. Does anyone know how to populate those in to dev? I probably cannot reboot the host for 3-4 days...

Do you need this for a storage drive or a cache drive? If its for storage on a SATA backplane, I would say the S3710 is the closer model. Samsung seems to have a slightly better price point with MLC and faster IOPS on the SM863a. Use their comparison chart on this page...

It most likely has a h 200 or h310 RAID controller. These are really bad because they have a queue depth of 25. If you have the full card not the mini mono, it can be flashed to an LSI 9211 firmware which has a queue depth of 600. As raid cards these things are absolutely horrible. But if it is...

If you are looking at Macrium, which I feel is a great product, you might also look at Easus Todo Backup, which is nearly identical to Macrium, but a couple more features, some of them are cloud based, but last I looked they had limited cloud options.

That does not sound very promising. If you need to run ZFS on a raid card, it had better be good, otherwise ZFS is optimized for a non-raid HBA card, where it can constantly monitor the bare drive state. If you are doing RAID5 of 7.2k sata on some junk raid card - ouch, all bets are off. I hope...

gluster or drbd+lvm... rubish raid card will give rubish results, test with low impact vms like linux or win7... a single ssd/nvme, no raid may do you better. you will learn fencing, barbed wired, etc ;) ZFS is a local file system, it does not have "live clustering" abilities, but if you had...

"a thing added like a hack".... definitely not, it is very robust, zfs send|receive is a standard function of any zfs implementation, PVE has just built a wrapper around it to schedule and track backups, and there is commitment from the PVE team to expand it in to the GUI someday. And it is...

another method is to add the unraid storage in to proxmox and then use the pve gui to do a hard drive move on the vm. the takes some good nix skills, not sure you will like it, this will let you move it to any format you desire, and the vm could even be running while you do it (slow). But you...

Short take: I would call that "not the whole story", but most likely (you say you have light use), you wont notice any issue for several years ... I know, sorry, blah blah here- Rest of the story and other important points- ZFS already writes a transaction log of *synchronous data* (zil) to the...

I bought a pair for $20 once ;) As long as it looks like a "pcie card", its not the mini, that will be really obvious. Flashing takes ~5-10 minutes and a couple reboots-...

You were real worried about ZFS and SSD TRIM - the 3ware does not support TRIM, unless they have come out with an update (i dont think broadcom cares to support them). This is what you could be looking at-...

Let us know how that 3ware turns out... benchmark it, know your performance as an actual number, and associate that with what you experience on your VM workload... I suspect it will do about 300mb/s on RAID6 - I wouldnt want too many win-vms touching that. I would not touch the 3ware with zfs...

I have been seeing a lot of users asking about ZFS and its magic abilities, here is a crusher for those on how bad it can get if you dont pay attention every last detail. Unfortunately the R730 is not on my bench, so today we have a Dell R720: 2x Xeon E5-2620, 32GB RAM, OS on standalone Samsung...

On your original system you talk of io issues... I am highly suspect of the 3ware, ~8 years back I used 20-30 of those on both windows and linux servers in bare metal and perf was on the low side, I used one on a low-load hypervisor with 1 VM! and it was unbearable, and it wasnt even RAID5/6. I...

Sounds like fun, if you run windows VM, I might suggest Anvils storage benchmark, or on linux, fio. You will want to run an initial quick test, and a 2nd test that exceeds RAM cache size (it may take a while to finish). Those T30 towers are monsters with no guts, have you looked at 2nd hand...

If you are determined to do ZFS, ideal config: - RAID1 for PVE boot. - RAID10 of 8 drives - 3x PCIe SSD, 2 for ZIL/SLOG, and 1 for L2ARC read cache. 4x desktop SSD, i dont know what to do with these, if you have slots, use them for a faster RAID10 array if your use case can put anything on...

You are getting close, but will need to do some edits on that conf... A couple observations- The 3Ware cards gave me terrible performance on another platform when I used to use them, in fact I think I had that exact model and had to ditch it for another card. That aside - it is not an HBA -...
