Ok, ok, I apologize for my badly expressed question. My problem is not
moving the data, but setting up the partition / filesystem while using the
volume manager.
The problem that hit me was that lsm (actually the kernel) seems to keep a
disk 'open' even after vold has been stopped - even the manual says this.
A reboot helped. I also found out that it is possible to run lsm on a
normal disk partition, i.e. it is possible to run ufs on partition 'a'
and have an lsm disk on partition 'g'.
Now, my next question....
I'm having trouble deciding whether to run advfs on top of raw partitions
or on lsm. Currently, the only place where lsm seems to gime more
flexibility is that it's easy to change the swap size. Most of the other
functionality can be achieved with advfs filesets.
So I'd like to hear experiance about this (not what the manual says,
but actual experiance), in terms of
a) performance, on a multiuser system, used for program development
b) reliability, would advfs be more reliable without lsm? (I'm not
planning to mirror any disks)
Personally I don't think striping would add much to performance in our
system (most files are very small, except the libs and executables,
these could be striped on the file level) but I might be wrong -
experince?
Also, whether mixing lsm and raw partitions is bad or good?
Any other good place to look for experience besides this list's archive?
regards, harald
PS. No, I don't have the printed manuals, so please don't refer to them.
I hate paper manuals, they're never where they're supposed to be, and
'grep' is hard top run.... DS.
