Question

LVM cached LV not available after reboot

Opened this issue 4 years ago · 4 comments

Created lvm cache according to wiki (https://github.com/quantum/esos/wiki/41_Advanced_Storage_Setup#lvmcache). After reboot LV Status is "NOT available" and LV not working. Checked this on VM in VMware.
Tried enabling rc.dmcache_enable in rc.conf without success.
Working in 1.3.9, not working in 2.0.0, 2.1.1.

Maybe some modules not loading in initrd.img? dm_cache, dm_cache_mq, dm_persistent_data, dm_bufio
