Hello,
were using centos 7 with FOG Version: 6971
bzImage Version: 4.13.4
bzImage32 Version: 4.5.0
and had requsted to extend /images mount as it was 78%
so as we have checked the first installtion was mounted on /dev/sdb
without creating any Physical volume\Volume group\Logical volume
so we couldnt extend it -
we had to make a new disk and mount it correctly and create pv vg and lv
and mounted it as XFS (and then i changed it to EXT4 cause i thout this caused the problems)
now, every time we try to pull an image to a new device we get 2 errors :
first : “EXT4-fs (ram0) : couldnt mount as ext3 due to feature incompatibilities”
second:“could not verify mount point, check if .mntcheck exists (/bin/fog.download)”
what do i do ? what did we did worng ?
thanks
