#4998: PANIC: cache destroy: still has partial slabs
------------------------------+---------------------------------------------
Reporter: idefix | Owner: axeld
Type: bug | Status: new
Priority: normal | Milestone: R1
Component: File Systems/BFS | Version: R1/Development
Keywords: | Blockedby:
Platform: All | Blocking:
------------------------------+---------------------------------------------
(The outcome looks a lot like ticket:3180, but the cause is different)
After encountering bug #3048 again, I decided to boot into a recent Haiku
installation (r34098) and check the volume:
{{{
~> mountvolume Build
Volume `Build' mounted successfully at '/Build'.
~> checkfs /Build/
checked 115475 nodes, 0 blocks not allocated, 0 blocks already set, 0
blocks could be freed
files 91926
directories 23520
attributes 17
attr. dirs 8
indices 4
~> mountvolume -u Build
}}}
After 5 seconds I get into KDL:
