I use backplanes from supermicro and silverstone. all configured to be dumb. The syslog does show that the OS notices the loss of a drive.

and before we start asking. 'what is your use case'please address my earlier questions related to the level of supprt regarding certain issues first then. So my raising a concern about ZFS is NOT amongst those.

I really do not mean disrespect @martin I respect and love proxmox and your team. But I have asked onthis forum some times if something would be covered by getting a subscription. The answer was always radio silence. So I am not sure what...

I am ringing the alarm bells.!!! ZFS should not be idle. I mean it is a small price to pay when every 30 seconds the tiniest of IO operation if done. Maybe every 1 hour or what ever seems useful. Doing no health checks is beyond my understanding at the moment. Can someone please shed some...

yes Fiona, A file create operation did trigger the pool to notice one of it's drives was missing. Is this intended behavior from the source code? If so then I would like to follow up with the OpenZFS people that build the code to learn about the reasoning behind this decision. It might be...

also, if I would run a FreeBSD system and do the same. Would it behave similar by being silent some of the times? The point I am trying to make is that I no longer believe it is the ZFS code. It might be there have been done some slight adaptations by the Proxmox team that allows for this weird...

anyone? How do I create an intensive IO operation so I can pull a disk from the pool involved in said operation? I do stress out though that this should not be needed in the first place. I'd be so much helped to learn why the current mechanism is how it is.

In an effort to shine more light on the matter I am trying to create a disk pull out scenario while the pool is in operation .. zpool status pool: notimportant state: ONLINE scan: resilvered 1.18T in 02:42:31 with 0 errors on Thu Nov 24 15:48:51 2022 config: NAME...

While I get my thoughts together again, can one of you please motivate why it would be good thing for ZFS (so in no way am I involving the proxmox team here) to only do health checks when there are IO operations? the more I think of it the more it does not make sense to me as one just a...

I had to break down my test because of... reasons ;( Ok, Please let me be your method then to settle this debate once and for all. What test shall I run to make it certain that there is an issue worth exploring or whether it is just a misunderstanding from a user perspective.

I have a superMicro and a SilverStone case. Both with HDD BackPlates configured to let the motherboard do all the "thinking" Hence the removal of a drive does get noticed by the OS in both cases, whether system a or b I tried this in. More to follow

I did not even start the test yet (and I will soon) but having a pool in active data flux should not be the only way to have ZFS tell you when things might go bad. I have more to say when I did my test

Inserting point, No I never did do this while the disks were in obvious operation. The pools on where I ran the tests were not in use so no changes. Hold on and I will do the same test but then force a change to the pool.

I changed the title of this thread to indicate it is no longer only about single disk pools

I am getting really worried. Just tried the drive removal from a 3 way mirrored pool on a different system. I pulled out one of the disks. syslog: Nov 24 08:37:24 pver1 kernel: ata6: SATA link down (SStatus 0 SControl 300) Nov 24 08:37:29 pver1 kernel: ata6: SATA link down (SStatus 0 SControl...

I can run the experiment again tomorrow. it was a test pool to test just these kind of scenarios syslog: Nov 23 20:14:15 pveasus smartd[3939]: Device: /dev/sda [SAT], removed ATA device: No such device. But ZFS and thus also ZED did not detect it thus no email was sent. I tried pulling a drive...

I am running proxmox 7.2.11 with zfs-zed/stable,now 2.1.6-pve1 amd64 zfs-initramfs/stable,now 2.1.6-pve1 all zfsutils-linux/stable,now 2.1.6-pve1 amd64 After taking out the only disk out of a hot swap bay in a single disk pool. zpool status still listed the pool as online including that disk...

or if someone knows of a linux distro with mirrored zfs root installer that would also solve the problem

tried all steps ib the link above. rebooted and can still log into localhost:8006 pve still running fine. apt remove --purge proxmox-ve Reading package lists... Done Building dependency tree... Done Reading state information... Done Package 'proxmox-ve' is not installed, so not removed 0...

SR-IOV is a luxury. Not needed. virtio is more than enough for basic needs.
