As i'm sure you all know, ext2 (and then ext3) is the most widely used linux fs... but some distros (SUSE & Debian) are now chosing to either use by default, or at least give the option of using ReiserFS.
What is it about ReiserFS that's so great exactly? I understand that it has a limitless... (6 Replies)

Hi everyone,
I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN?
At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the... (2 Replies)
I'm trying to find a correct command that will mount a filesystem ext3 the device /dev/sda1 to mount point /mnt/usb but not allow any programs to run from it.
I want to be honest as I've read the forum rules... This is a homework question BUT, i'm generally interested in the correct process and... (3 Replies)

echo "- - -" > /sys/class/scsi_host/host<number>/scan
nice now
after that I tried to create a folder in /

I am researching the cause of an issue. The SAN file system /export/pools/zd-xxxxxxxxxxx is having a high amount of read traffic even though it is empty. It is ZFS with MPXIO. Any ideas? It's really strange considering the file system is empty, and I don't see any errors.

lvdisplay
LVDISPLAY(8) System Manager's Manual LVDISPLAY(8)NAME
lvdisplay - display attributes of a logical volume
SYNOPSIS
lvdisplay [-a|--all] [-c|--colon] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--maps] [--nosuffix] [-P|--partial] [--units hHbB-
sSkKmMgGtTpPeE] [-v|--verbose] [--version] [LogicalVolumePath [LogicalVolumePath...]]
lvdisplay --columns | -C [--aligned] [-a|--all] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--noheadings] [--nosuffix]
[-o|--options [+]Field[,Field]] [-O|--sort [+|-]Key1[,[+|-]Key2[,...]]] [-P|--partial] [--segments] [--separator Separator] [--unbuffered]
[--units hHbBsSkKmMgGtTpPeE] [-v|--verbose] [--version] [LogicalVolumePath [LogicalVolumePath...]]
DESCRIPTION
lvdisplay allows you to see the attributes of a logical volume like size, read/write status, snapshot information etc.
lvs (8) is an alternative that provides the same information in the style of ps (1). lvs is recommended over lvdisplay.
OPTIONS
See lvm for common options and lvs for options given with --columns.
--all Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as
mirrors, but which are not independently accessible (e.g. not mountable). For example, after creating a mirror using 'lvcreate -m1
--mirrorlog disk', this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.
-c, --colon
Generate colon separated output for easier parsing in scripts or programs. N.B. lvs (8) provides considerably more control over the
output.
The values are:
* logical volume name
* volume group name
* logical volume access
* logical volume status
* internal logical volume number
* open count of logical volume
* logical volume size in sectors
* current logical extents associated to logical volume
* allocated logical extents of logical volume
* allocation policy of logical volume
* read ahead sectors of logical volume
* major device number of logical volume
* minor device number of logical volume
-m, --maps
Display the mapping of logical extents to physical volumes and physical extents. To map physical extents to logical extents use
pvs --segments -o+lv_name,seg_start_pe,segtype.
--columns | -C
Display output in columns, the equivalent of lvs. Options listed are the same as options given in lvs (8).
Examples
"lvdisplay -v /dev/vg00/lvol2" shows attributes of that logical volume. If snapshot logical volumes have been created for this original
logical volume, this command shows a list of all snapshot logical volumes and their status (active or inactive) as well.
"lvdisplay /dev/vg00/snapshot" shows the attributes of this snapshot logical volume and also which original logical volume it is associated
with.
