  • [6.7.0-rc1] misreading cache drive size/used/free

      • Solved Minor

    just took the plunge on 6.7.0-rc1 on 1 server with a 1TB SSD for Cache and thought I read somewhere else someone is seeing the same issue but cant find it (sorry if this is a duplicate).

    my 1TB is being reported as a 8.3GB drive showing an unsually low amount of used and free I have tried the BTRS balance and Scrub without a change

    I think the other reports had to do with displaying much larger than true, as in PB instead of TB.

     

    Where are your diagnostics?

    Looks to me like some confusion because you removed one of the cache devices and that device was later mounted and unmounted by UD, rebooting should clear the issue.

    i did have a 256GB SSD on there from 6.6.6 and kept it until the 6.7.0-rc1 install I then stopped the array

     

    removed the 256GB one (hated loosing 500GB to the raid 1 setup) and started the array (did not use New Config)...there was a check box to allow the missing cache by the start array option...

    thanks for the advice ill reboot after the mover is done and current downloads from sabnzbd are completed.

    That issue was with the UD plugin and didn't apply to array drives.
