kstat -p -m zfs -n arcstats -s size returns

this values is approx (7.61 GB) but my Physical Memory size is only 6144 Megabytes.
Can this happen ?
If your NGZ physical memory is capped, this can indeed happen. kernel memory is shared by all zones so is not restricted by capping.

Can you please let me know how to get the memory usage?.
Thanks,

Hi,
I have a server (BL460c) with 32G of physical RAM.
It currently only uses approx 5% its capacity but will use more (not sure how much more) pending the launch of further applications.
If I need to build another node of similar functionality should I consider downgrading the physical... (2 Replies)
Hello,
in one default UFS filesystem we have 8K block size (bsize) and 1K fragmentsize (fsize). At this scenary I thought all "FileSytem IO" will be 8K (or greater) but never smaller than the fragment size (1K). If a UFS fragment/blocksize is allwasy several ADJACENTS sectors on disk (in a ... (4 Replies)

zdb(8) System Administration Commands zdb(8)NAME
zdb - ZFS debugger
SYNOPSIS
zdb pool
DESCRIPTION
The zdb command is used by support engineers to diagnose failures and gather statistics. Since the ZFS file system is always consistent on
disk and is self-repairing, zdb should only be run under the direction by a support engineer.
If no arguments are specified, zdb, performs basic consistency checks on the pool and associated datasets, and report any problems
detected.
Any options supported by this command are internal to Sun and subject to change at any time.
EXIT STATUS
The following exit values are returned:
0 The pool is consistent.
1 An error was detected.
2 Invalid command line options were specified.
