Jul 28, 10 0 1. Hey guys! Need your help please! I am using Proxmox 2. Please help! Dec 30, 22 Do you see them mounted eg. Well, in that case probably Proxmox created dirs for some PVE storage you configured in the zfs root. You're safe to delete everything there before mounting the zfs datasets but do check it before doing so.

Or arrange startup order so PVE startup scripts start after the zfs script in init. In short, make sure the zfs root dir is empty when mounting your zfs datasets.

Aug 19 pve-rxd1 zpool[]: invalid or corrupt cache file contents: invalid or missing cache file. Reactions: Psilospiral. Stoiko: You are correct. My lack of proper cache file was the root of the issue causing problems with mounting of my ZFS pool at boot. I entered: Code:. Aug 20 pve-rxd1 systemd[1]: zfs-mount.

Thread starter Avery Freeman Start date Apr 19, Avery Freeman Member Reaction score: 15 Messages: But now I'm starting to think maybe it was a bad idea I haven't had time to properly nail down what's going on, it seems beyond me at this point. Exporting the pool and then immediately importing seems to work but is a frustratingly bad solution. Anyone ever seen this before?

Also, seek times seem awfully slow once pool is imported. Does that have to do with the recent import? It's killing me. Edit: I overlooked a significant flag which in my experience was not required to mount ZFS in Linux, and it did require me having help because apparently it was staring me right in the face and I just didn't see it I guess for me it's RTFMx2 or 3.

Last edited: Apr 21, Pretty much impossible to comment on this because you're hardly giving us any useful information. For example, what does: zpool status tell you? Or zfs list? SirDice Administrator Staff member. Avery Freeman said:.This state means that ZFS was unable to open the device when the pool was first accessed, or the device has since become unavailable. If the device causes a top-level virtual device to be unavailable, then nothing in the pool can be accessed.

Otherwise, the fault tolerance of the pool might be compromised. In either case, the device just needs to be reattached to the system to restore normal operations. For example, you might see a message similar to the following from fmd after a device failure:.

To view more detailed information about the device problem and the resolution, use the zpool status -x command. For example:. You can see from this output that the missing c1t1d0 device is not functioning. If you determine that the device is faulty, replace it. Exactly how a missing device is reattached depends on the device in question. If the device is a network-attached drive, connectivity to the network should be restored. If the device is a USB device or other removable media, it should be reattached to the system.

If the device is a local disk, a controller might have failed such that the device is no longer visible to the system. In this case, the controller should be replaced, at which point the disks will again be available. Other problems can exist and depend on the type of hardware and its configuration. If a drive fails and it is no longer visible to the system, the device should be treated as a damaged device.

Follow the procedures in Replacing or Repairing a Damaged Device.

After a device is reattached to the system, ZFS might or might not automatically detect its availability. If the pool was previously faulted, or the system was rebooted as part of the attach procedure, then ZFS automatically rescans all devices when it tries to open the pool.

If the pool was degraded and the device was replaced while the system was running, you must notify ZFS that the device is now available and ready to be reopened by using the zpool online command. For more information about bringing devices online, see Bringing a Device Online.

An attempt will be made to activate a hot spare if available. Sufficient replicas exist for the pool to continue functioning in a degraded state. Then, use the zpool online command to bring online the replaced device. For example: zpool online tank c1t1d0 As a last step, confirm that the pool with the replaced device is healthy.

For example: zpool status -x tank pool 'tank' is healthy Physically Reattaching a Device Exactly how a missing device is reattached depends on the device in question. For example: zpool online tank c0t1d0 For more information about bringing devices online, see Bringing a Device Online.Asked by Derek Slama.

How do you take someone back after they cheated

So far, everything I do results in the Network cards being unrecognized by XenServer after a reboot if it's in a Pool if it's a Slave. The master does reboot properly. Typically, this is after a patch, but I can also just reboot the Machine and it'll happen. I can go into the console and run the Stack restart command as pictured and networking will come back and it will rejoin the Pool.

I had all NICs connected. Did not create a Management Bond. As independent servers I was able to install patches and reboot without issue from XenCenter. As soon as I created a pool, I was able to add the servers into it, but then rebooting them caused the Network issue.

I've tried only connecting 1 NIC to the Linksys switch. Base install of XenServer. No patches applied. Created a XenPool. Used XenCenter to apply SP1. It applied to XenServer02 master and rebooted. Then it applied to XenServer01 and it never came back. I've tried some other things like all default BIOS settings. Changing the Network cards around. Turning off the Mirrored SD cards and just using 1. I've tried to apply all patches before creating a pool and it still happened.

I've tried having the pool built with a different Master.

I feel like it's something in the XEN software because everything is peachy until they are in a Pool. If not a hardware or BIOS settings or issue, I would recommend ejecting the server from the pool, deleting all interfaces excpt one non-bonded NIC to be used as the primary management interface on the same network as that of the pool, of course and re-join it to the pool -- it should then pick up all the interfaces and bonds and reconfigure them.

In the worst case, you may have to manually adjust NIC orders with the interface-reconfiguration utility to get them to match. If you run "ifconfig" on the server, do you see a list of network devices? Also, do you have NTP properly set up on all hosts? You will be able to leave a comment after signing in.
