I'll look into these threads: https://forum.proxmox.com/threads/local-lvm-disk-lost.75551/ https://forum.proxmox.com/threads/lvm-issue.29134/#post-146250

Hi all, One of my cluster-nodes crashed the other other day and trashed its local-lvm. After some work, the local-lvm is up again but the web-gui shows the raw vm-disks, when in fact there is no trace whatsoever on the node it self. Where are these coming from, and how do I get rid of them? The...

After 1h 55m it's seems to be online again. Htop says some kind of check is going on. Pve-data_tmeta, seems to be the lvm metadata that got borked for some reason when the node rebooted? Anything I can do to prevent stuff like this happening in the future?

Hello all, So I ran into this a few hours ago. Can't access any kind of terminal to run a fsck manually. Please see the attached pic. Do I just wait or is there some magic I can use to make stuff happen (faster)? The server is a Dell R710 with 6x 2 TB drives in a raid5 fashion, using a...

Aha, thanks! Discovered that feature recently on our proxmox-lab--ceph-cluster at work, but didn't quite know how and when to use it.

That's an interesting angle. Thanks!

I see what you mean. However, I have five containers, each set up with 4 GB of storage, and totalling 20 GB. With that in mind, I still don't see where those 88 gigs are coming from.

Hi all, I'm currently running a three-node cluster with proxmox 6 using lvm-storage but would like to move to ceph and zfs. Two of the cluster nodes are rack servers and the third is a witness node with less than stellar storage capabiliites. FWIW, this is a home lab cluster running my personal...

I still don't get it. Migrating a 4 GB container to a node that has a thin-lvm with about 60ish GB free. Where does it get I've provisioned 88 GB for this container? The migration went through just fine I think. Can somebody please help me understand this? 2021-11-25 16:41:13 shutdown CT...

More speed info. root@cyndane5:~# fdisk -l /dev/sda Disk /dev/sda: 9.1 TiB, 9999220736000 bytes, 19529728000 sectors Disk model: PERC H710 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes...

I'm kinda' reluctant to initiate a migration of two vm's that are over 2 TB each, because of this. If anybody has any ideas on how to tune and streamline disk speeds with the current raid-5 arrays I'm all ears! I realize raid-5 are not that efficient, but that's what I can afford ATM! For a...

Are these okay numbers? Have no reference really, except a feeling that fifteen minutes to move a 32GB vm is too long. I kinda' expected faster migrations... The migration is done from a Dell R710 to a Dell R720. Both nodes in the cluster each uses battery-backed raid5 with 6x 2 TB Seagate...

The guest!

Thanks for this comment, it set me on the right track! Had similar issues as OP. All fixed now. It was indeed an issue with NFS. I'll look into this some more at a later stage, when I've confirmed the problem is solved.

Thanks AndyRed! I've been meaning to look into HAproxy seeing as how it seems to be a popular goto-proxy-thing. Your input may put on the track for testing, thanks!

From my personal point of view scripted disk reductions are iffy, as things may go wrong. I prefer to do this manually and reviewing each step before I continue to the next step. This is Dangerous Stuff(tm). :-)

Nevermind, found out how. Documenting it here for posterity. :-) On your proxmox node, do this. List the containers: pct list Stop the particular container you want to resize: pct stop 999 Find out it's path on the node: lvdisplay | grep "LV Path\|LV Size" For good measure one can run a...

Could you please elaborate on this, or better yet - point to some pve-documentation on decreasing disk size?

Excellent, thank you!

Just recently started looking into containers in Proxmox. The nesting bit over here; https://pve.proxmox.com/wiki/Linux_Container, is a bit lacking for my part. "nesting=<boolean> (default = 0) Allow nesting. Best used with unprivileged containers with additional id mapping. Note that this...
