Common scenario when you need to bind VM to particular VLAN is to create bridge on host node and use this bridge interface in Network section of particular VM. Is there any solution to not create bridge interfaces at all? Network options page allows only bridge-type interfaces to be chosen. So...

Running lxc on 7.1. Use ceph@ssd as rbd. Container runs rabbitmq with 5-10K rps. What could be wrong with such large system and interrupts values? top - 17:01:09 up 5 days, 15:03, 1 user, load average: 77.19, 93.43, 96.93 Tasks: 1755 total, 28 running, 1727 sleeping, 0 stopped, 0 zombie...

I clearly understand that, just wanted to remind of the issue.

Thank you a lot. Will check and report for any issues.

Any solutions other than set kernel.unprivileged_userns_clone to 0? Or is fixed kernel version released?

How could I enable lazytime mount option for lxc containers? Current mount options have only noatime nosuid when checking Mount point. P.S. Probably it may be done by direct editing of .conf file at /etc/pve/lxc?

Looks as I solved it. Key problem was to place correct data into /etc/pve/priv/ceph.client.bootstrap-osd.keyring and /var/lib/ceph/bootstrap-osd/ceph.keyring files. So, you just need to get auth data for client.bootstrap-osd (real key is replaced): # ceph auth ls // skipped and screened...

Upd. Looks as I need to carefully read Cephx Config Reference.

Hi, I'm trying to create Bluestore-backed OSDs using partitions not complete disk. Assuming that /dev/sda4 will be future OSD (placed on HDD drive), I created separate partition on SSD for DB/WAL. First try: # pveceph osd create /dev/sda4 -db_dev /dev/sdc1 -db_size 54 unable to get device info...

Hi, Has anybody succeeded with running rootless (as ordinal user not root) Docker inside unprivileged LXC container? I followed this official guide: https://docs.docker.com/engine/security/rootless/. Installation failed with the following message:dockerd-rootless.sh[355]: [rootlesskit:parent]...

Hi, I added several dozens SSDs to Ceph cluster and found that Proxmox reports Apply latency for them from 200 to 500 ms. I checked with iostat program - zero activity. What could be wrong with them? P.S. No migration process happens - they are linked to separate 'root' container.

Try to add nomodeset to kernel boot settings.

Looks like Linbit chose the way that Apple has taken once: no other players. Although I was successful with making master+2slaves DRBD cluster in production.

Hi, Some notes: 1. Resizing from Proxmox UI failed with message 'VM 102 qmp command failed - VM 102 qmp command 'block_resize' failed - Could not resize: Invalid argument' 2. Successfully resized image on ceph with 'qemu-img resize -f rbd rbd:rbd/vm-102-disk-1 48G' 3. But Proxmox UI and VM...

Please, paste cat /proc/mdstat output.

Hi, I found simple way to get all CT/VMs unusable. Simply delete ceph pool in Ceph->Pools->Remove. No warnings or locks even it's used in any way. Running pve-manager/4.2-15/6669ad2c (running kernel: 4.4.10-1-pve) Regards, Alex

For those who are interested in creating osd journal on separate partition (not disk) here are the steps: (assume that sda3 and sdb3 - 5GB partitions for journal, sdc and sdd - disks for osd data) 1. Create partition with correct size. If using fdisk partition's size should be 10483712 sectors...

Very strange/bad. Even running ceph-disk prepare --fs-type xfs --cluster ceph --cluster-uuid 908ceb45-91b6-4c31-8ede-00acab17c9ef --journal-dev /dev/sdc /dev/sda3 deletes /dev/sda3 :(

Hi, I use Proxmox 4.2 and wonder if things are ok: # pveceph createosd /dev/sdc -journal_dev /dev/sda3 create OSD on /dev/sdc (xfs) using device '/dev/sda3' for journal Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header...
