TASK DESCRIPTION
WMCS instances have some extra disk space which is not mounted by default. It can be mounted on /srv using role::labs::lvm::srv. There is a legacy class role::labs::lvm::mnt (which mount it on /mnt) which is deprecated and should be removed entirely.
Continuous integration was among the early adopters of /mnt. They all got migrated to /srv via T146381.
Labs instances should be switched to role::labs::lvm::srv @hashar wrote a migration guide on https://gerrit.wikimedia.org/r/#/c/330412/ :
- switch from role::labs::lvm::mnt to role::labs::lvm::srv
- run puppet
- kill anything that might be using /mnt (lsof /mnt)
- manually umount /mnt
- ensure /srv is mounted
- VERIFY /mnt is no more refered to in /etc/fstab
- failure to do so would cause the instance to be deadlocked on the next reboot
