Hi Trifo75,
Quote:
Well, you have a LOT of disks in this VG. 29 right now, and you would like to put the 30th in. This is big. When you use the factor "6" as in your example, you can have only 21 PV-s in the VG. Try a smaller factor. Or omit factor entirely to let chvg choose a value.
If I use small factor, I can have more PVs but the max PP of PV is smaller which cannot afford to add 1TB disk which around 8000 PPs.
Quote:
Also - if you have the opportunity to do that - you should recreate that VG with bigger PP size - 1GB is not too big to a 5TB volume group. Also, if it is not defined as "big VG", the PV limit is 32 which is scary close.
How if I convert it to scalable VG? it can add the disk regardless of the size as well as "Max PP per PV" parameter?

I guess first I'll have to decrease the size of other partition(s) in rootvg?

I am running solaris 10 with Veritas. I want to extend a filesystem. It's an oracle partition (/ora12). How can I find out if there is space available to expand the filesystem and then how does one extend it.
I'm from the HPUX world and so LVM was always how I did things.
Thanks

NAME
mlib_SignalUpSample_S16_S16, mlib_SignalUpSample_S16S_S16S, mlib_SignalUpSample_F32_F32, mlib_SignalUpSample_F32S_F32S - signal upsampling
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalUpSample_S16_S16(mlib_s16 *dst, const mlib_s16 *src, mlib_s32 factor, mlib_s32 phase, mlib_s32 n);
mlib_status mlib_SignalUpSample_S16S_S16S(mlib_s16 *dst, const mlib_s16 *src, mlib_s32 factor, mlib_s32 phase, mlib_s32 n);
mlib_status mlib_SignalUpSample_F32_F32(mlib_f32 *dst, const mlib_f32 *src, mlib_s32 factor, mlib_s32 phase, mlib_s32 n);
mlib_status mlib_SignalUpSample_F32S_F32S(mlib_f32 *dst, const mlib_f32 *src, mlib_s32 factor, mlib_s32 phase, mlib_s32 n);
DESCRIPTION
Each of these functions performs upsampling.
For monaural signals, the following equation is used:
dst[i] = src[k] if i == k*factor + phase
dst[i] = 0 if i != k*factor + phase
where k = 0, 1, ..., (n - 1); i = 0, 1, ..., (n*factor - 1).
For stereo signals, the following equation is used:
dst[2*i] = src[2*k] if i == k*factor + phase
dst[2*i] = 0 if i != k*factor + phase
dst[2*i + 1] = src[2*k + 1] if i == k*factor + phase
dst[2*i + 1] = 0 if i != k*factor + phase
where k = 0, 1, ..., (n - 1); i = 0, 1, ..., (n*factor - 1).
PARAMETERS
Each of the functions takes the following arguments:
dst Output signal array.
src Input signal array.
factor Factor by which to upsample. factor >= 1.
phase Parameter that determines relative position of an input value, within the output signal. 0 <= phase < factor.
n Number of samples in the input signal array.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
