Re: [pve-devel] use our own format for LXC containers
In future, we can now also add additional mount entries like: rootfs: local:101/subvol-101-disk-1.raw,size=4 mount0: faststore:101/subvol-101-disk-1.raw,size=1,mp=/mnt/faststore mount1: slowbigstore:101/subvol-101-disk-1.raw,size=1024,mp=/mnt/slowbigstore I wonder if we could use something generic like hdd0: local:101/subvol-101-disk-1.raw,size=4,mp=/ hdd1: faststore:101/subvol-101-disk-1.raw,size=1,mp=/mnt/faststore hdd2: slowbigstore:101/subvol-101-disk-1.raw,size=1024,mp=/mnt/slowbigstore ? - Mail original - De: dietmar diet...@proxmox.com À: aderumier aderum...@odiso.com Cc: pve-devel pve-devel@pve.proxmox.com Envoyé: Jeudi 6 Août 2015 16:59:00 Objet: Re: [pve-devel] use our own format for LXC containers In future, I want to implement 'subvol' for normal directories (maps to simple subdirectories).

I wonder if we could use something generic like hdd0: local:101/subvol-101-disk-1.raw,size=4,mp=/ I prefer 'rootfs' instead, because 'rootfs' has fixed mp '/', and is a required option. hdd1: faststore:101/subvol-101-disk-1.raw,size=1,mp=/mnt/faststore hdd2: slowbigstore:101/subvol-101-disk-1.raw,size=1024,mp=/mnt/slowbigstore those are optional, and have a montpoint. ___ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel

Ok.

Re: [pve-devel] use our own format for LXC containers
Do you still write the config file at lxc format for lxc-start ? (maybe on each ct start ?) If yes, I'm not sure, but I think it's possible to pass key=values to lxc-start command line, -s, --define KEY=VAL Assign value VAL to configuration variable KEY. This overrides any assignment done in config_file. - Mail original - De: dietmar diet...@proxmox.com À: pve-devel pve-devel@pve.proxmox.com Envoyé: Jeudi 6 Août 2015 12:20:13 Objet: [pve-devel] use our own format for LXC containers Hi all, we finally use our own format for lxc containers. The patch touch most parts of the existing code, so it was quite large (sorry). To test, you need to update the following packages from git: pve-cluster lxc pve-container pve-manager We now store LXC configuration as normal files at: /etc/pve/lxc/vmid.conf Here is an example: --- arch: amd64 cpulimit: 1 cpuunits: 1024 hostname: CT105 memory: 512 net0: name=eth0,hwaddr=0E:18:24:41:2C:43,bridge=vmbr0 ostype: debian rootfs: subpool:subvol-105-rootfs,size=2 swap: 512 Please test and report bugs ;-) Note: The new format is not compatible with the old one, so you will loose existing containers when you update. - Dietmar ___ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel ___ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel

Re: [pve-devel] use our own format for LXC containers
Sure, yes. What problem do you want to solve?
no special problem, just remove a file write at each start
BTW, I have read the new code, I don't have tested it yet,
but
if ($scfg-{type} eq 'dir' || $scfg-{type} eq 'nfs') {
+ if ($size 0) {
+ $volid = PVE::Storage::vdisk_alloc($storage_conf, $storage,
$vmid, 'raw',
+ vm-$vmid-rootfs.raw,
$size);
+ } else {
+ $volid = PVE::Storage::vdisk_alloc($storage_conf, $storage,
$vmid, 'subvol',
+ subvol-$vmid-rootfs, 0);
+ }
I think this is wrong for $size == 0 ? (subvol is related to zfs right ?)
