[BUG] WALinuxAgent fails to mkfs.btrfs on the resource disk
Opened this issue · 0 comments
cadeavil-msft commented
When configured to set up the resource disk with a BTRFS filesystem, waagent calls 'mkfs.btrfs -F' (upper-case 'F'). This is wrong: 'mkfs.btrfs' expects a lower case '-f' to force recreating a filesystem if one already exists. In fact, 'mkfs.btrfs' does not even have a '-F' option.
Note: Please add some context which would help us understand the problem better

2. Serial console output: N/A
3. Steps to reproduce the behavior.
a. configure waagent to format the resource disk & create a BTRFS partition:
# Format if unformatted. If 'n', resource disk will not be mounted.
ResourceDisk.Format=y
# File system on the resource disk
# Typically ext3 or ext4. FreeBSD images should use 'ufs2' here.
ResourceDisk.Filesystem=btrfs
# Mount point for the resource disk
ResourceDisk.MountPoint=/mnt/resource
b. stop/deallocate the VM, and start it again. The 'mkfs-btrfs' failure will have been logged as above.
