Hi,
I'm trying out reiser4 discard feature (openSUSE with doiggl's package
under VirtualBox) and getting this repeated warning. So I'd like to know
if it is a known issue and how serious it is.

www.namesys.com for a description of Reiser4.

Hi Gleb,
It means that your sdb1 doesn't support TRIM command.
sdb1 is virtual device, correct?
Edward.

Ok, thanks for clarification. Yes, it is VirtualBox VDI disk image.
It turned out that VirtualBox GUI only allows to switch "--nonrotational
on", so after issuing "VBoxManage --discard on" in addition I got rid of
this warning.
Best regards,
Gleb
