993.0. "lsm, advfs and size differences" by DAIVC::SUGIYONO () Wed Jan 29 1997 19:03
Dear All,
Refers to the answer of my question on the LSM notes 745, I posted
the following question on this forum:
Why there are differences (in size) between volume size (that we get from
# volprint -htA) and the size of the volume after mounted (that we get from
# df) ? Meanwhile some other volume has no differences (as you see in the
following attachment, there are no size differences between rootvol and /
file system; but there are any size differences among other volumes).
FYI: DU Vers. 4.0A.

Swap partition /dev/vol/rootdg/swapvol (default swap):
Allocated space: 35163 pages (274MB)
In-use space: 1 pages ( 0%)
Free space: 35162 pages ( 99%)
Total swap allocation:
Allocated space: 35163 pages (274MB)
Reserved space: 4535 pages ( 12%)
In-use space: 1 pages ( 0%)
Available space: 30628 pages ( 87%)
Can somebody tell me the reason for these differences please?
Thanks in advanced.
