    Very high IO Delay on any load

    The steps are here, but what you are saying is new an foreign to me. Since I am rebuilding I am worried about making sure my backups are 100% guaranteed of being restorable. Could you please expound on this?

    Very high IO Delay on any load

    Doing more research, both the of rear USB ports on my Dell PowerEdge R730 are definitely USB 3. However, I do have a USB to PS/2 Keyboard and Mouse adapter plugged in back there going to one of the ports for my KVM. There isn't any chance that could cause the internal USB hub to go all 2.1 only...

    Very high IO Delay on any load

    It is a USB 3 drive and port. EDIT: So after my comment I went and checked. Like I thought, both the Drive and the port are USB 3. HOWEVER: the output of lsusb -vv shows me that the bcdUSB line states 2.10. Obviously the OS is not recognizing and connecting it as USB 3. Hmm.... Bus 002 Device...

    Very high IO Delay on any load

    I need a better option to do these backups. I don't know if I am just hitting the limitation on how fast I can write t o the external USB drive, or if there is something deeper broken about my ProMox I/O. I gave myself a 12 hour windows of downtime to do this and there was no way I was going to...

    Very high IO Delay on any load

    I got the two additional hard drives in. I have scheduled a maintenance window this weekend to convert the existing RAID-Z to a Stripe/Mirror setup. With the additional two drives the final raw capacity should be on par with my current capacity. Once this is done I will report back and let...

    Very high IO Delay on any load

    Yea, we host everything in house. When I say local hosting, that is exactly what I mean. We are probably about the only one in our area that does it. If you are a local business, and you need a website designed and hosted by people you are sit down with in person, and then get it hosted in the...

    Very high IO Delay on any load

    Available resources and $$ brother. The ProxMox server is brand new hardware, it was not cheap, and I had to push to get it. the ESXi servers it is replacing are 10 years old. Fine for what I will repurpose them for, but not generally what I want to continue to run my VMs on. Have you priced...

    Very high IO Delay on any load

    Actually, once I get the kinks worked out and I can migrate all the ESXi 5.0 VM to the ProxMox server, I will have an older but still OK Dell storage chassis I can repurpose for backup. It currently is the storage for two vSphere servers. Also, it is not critical the VMs themselves get images...

    Very high IO Delay on any load

    Ok. I have asked for an 8TB, external, USB 3 drive and two additional 2TB drives of the same model number currently in the server. Hopefully this is not too much friction for the boss/owner. I will report back when I have progress to report. Thank you all.

    Very high IO Delay on any load

    That is in line with what I was thinking. The fault detection and self healing are primary reason I wish to use it. So to "build" it properly (because RAID1+0 and RAID0+1 are have vastly different manners in which you can lose drives and still recover) I think what I want to do is create a tank...

    Very high IO Delay on any load

    I just thought of an additional question. When I rebuild this into a striped mirror, which scenario is preferable and why: ZFS RAID S+M or hardware (PERC H330 RAID Controller) RAID10 with the single logical volume as a ZFS Pool? This is not a battery backed controller, but as was mentioned, it...

    Thank you to everyone who has responded. I have a lot to do it looks like. Here is is: root@the-verse:~# arc_summary ------------------------------------------------------------------------ ZFS Subsystem Report Thu Oct 26 06:28:17 2017 ARC Summary: (HEALTHY)...

    Very high IO Delay on any load

    Thank you very much for taking the time to read all of that and providing me with a very usable answer to my questions. Noting my second goal, I already guessed a rebuild was in order. If I get a 8TB USB 3 external drive for backups, will that work to rebuild? Any guesses on how long I would...

    Very high IO Delay on any load

    I am getting very high IO Delay on any kind of a load. It basically stalls all VMs. We are a web host and we have five CloudLinux/cPanel VMs (all with about 100 sites each), A Windows 2016/Plesk VM, and a CentOS7/Sentora VM running. When this happpens all sites stop responding, I get kernel:NMI...
