I know that zdb is private and totally unstable, but could we get
the manpage for it to at least say what the LSIZE, PSIZE and ASIZE
columns mean please?
See Section 2.6 of the ZFS On-Disk Specification:
-- BEGIN QUOTE --
lsize: Logical size. The size of the data without compression, raidz or
gang overheard.
psize: Physical size of the blok on disk after compression.
asize: Allocated size, total size of all blocks allocated to hold this
data including any gang headers or raidz parity information.
If compression is turned off and ZFS is not on raidz storage, lsize,
asize and psize will all be equal.
All sizes are stored as the number of 512 byte sectors (minus one)
needed to represent the size of this block.
-- END QUOTE --
Thankyou for the pointer.
/me slaps self on side of head for research failure
I'll go and do some more reading :)
cheers,
