So, that's the idea... The FS I want grown, is /dev/vda9 that is mounted as /opt. I resize the this via PVE web portal. The /dev/vda had 2 TB and I added more 500 GB... Cfdisk, and parted as well, show that just after /dev/vda9, I have more 500 GB free space I just want to know, with some

Oops, yes, I've even used it that way. Also, LVM is helpful here, because you can migrate a running LV to a new disk in the VG, then delete the original disk, then grow the LV - all without downtime. -Adam On February 3, 2016 1:07:29 AM CST, Wolfgang Bumiller wrote: >>

Ah. Now I begin to understand what you're after. (All commands from memory - check man pages for syntax) Create a new disk in PVE. (Suggest creating at as virt-scsi, not virtio, so that you get TRIM support.) pvcreate /dev/vdb vgcreate DATAVG /dev/vdb lvcreate -l90%VG -n DATALV DATAVG #leave

Gilberto, I have used btrfs for almost 2 years and like it alot for its features. I've not used it with proxmox though. Matter of fact I just changed my machine to use btrfs raid10 (btrfs raid not mdm raid). In btrfs this is only 1 command: reference: btrfs with multiple devices

As far as I know, there is still one big problem with BTRFS for Proxmox: Running a thin-provisioned VM (i.e. QCOW2) on top of a BTRFS filesystem on top of a regular spinning-rust HDD produces **extremely bad** performance. Running the identical system but on ext2/ext3/ext4 produces the

Well I almost do it, 'cause one of feature I appreciate in btrfs is the hability to increase or decrease disk size. I know LVM can do it as well, but LVM are always on top whatever X Filesystem. So do you have more layers... Btrfs is direct into the device. Or am I wrong?! 2016-02-02 11:30
