Is there a way to determine the number of available spare sectors on a disk ? as it may be useful for notifying a user to take a backup of the disk before it runs into a medium error. (6 Replies)
Hello,
Am basically working on VxFS filesystem and while tracking the file, I got stuck at one point.
As I am able to locate the superblock(it is at offset 1024 from the start of partition). And from superblock I got the sector no. of "OLT extent".
By jumping to the sector no where OLT... (1 Reply)

Hello...
i got an error in my SCO OpenServer 6. the error is:
msgcnt 1 vxfs: mesg 016: vx_ilisterr - / file system error reading inode 373
Can anyone help me? (1 Reply)
when I try to enter the value 424 for "data sectors/track" in format menu, it returns this error:
`424' is out of range.
is that hard drive parameter important? what to enter?
thanks. (2 Replies)

Hi
A mismatch occurred on my system (Debian, Sid). I've got 3 disks sda, b, c.
Unfortunately, when I was adding a third disk (sdc) it all finished so that both sdb and sdc now have a boot flag. So, the first thing I would like to find out is which disk the system now boots from: sdb or sdc? In... (0 Replies)

lvextend
LVEXTEND(8) System Manager's Manual LVEXTEND(8)NAME
lvextend - extend the size of a logical volume
SYNOPSIS
lvextend [--alloc AllocationPolicy] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--noudevsync] [-i|--stripes Stripes [-I|--stripesize
StripeSize]] {-l|--extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}] | -L|--size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]}
[-f|--force] [-n|--nofsck] [-r|--resizefs] [-t|--test] [-v|--verbose] LogicalVolumePath [PhysicalVolumePath[:PE[-PE]]...]
DESCRIPTION
lvextend allows you to extend the size of a logical volume. Extension of snapshot logical volumes (see lvcreate(8) for information to cre-
ate snapshots) is supported as well. But to change the number of copies in a mirrored logical volume use lvconvert(8).
OPTIONS
See lvm for common options.
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
-l, --extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
Extend or set the logical volume size in units of logical extents. With the + sign the value is added to the actual size of the
logical volume and without it, the value is taken as an absolute one. The number can also be expressed as a percentage of the total
space in the Volume Group with the suffix %VG, relative to the existing size of the Logical Volume with the suffix %LV, of the
remaining free space for the specified PhysicalVolume(s) with the suffix %PVS, as a percentage of the remaining free space in the
Volume Group with the suffix %FREE, or (for a snapshot) as a percentage of the total space in the Origin Logical Volume with the
suffix %ORIGIN. The resulting value is rounded upward.
-L, --size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Extend or set the logical volume size in units of megabytes. A size suffix of M for megabytes, G for gigabytes, T for terabytes, P
for petabytes or E for exabytes is optional. With the + sign the value is added to the actual size of the logical volume and with-
out it, the value is taken as an absolute one.
-i, --stripes Stripes
Gives the number of stripes for the extension. Not applicable to LVs using the original metadata LVM format, which must use a sin-
gle value throughout.
-I, --stripesize StripeSize
Gives the number of kilobytes for the granularity of the stripes. Not applicable to LVs using the original metadata LVM format,
which must use a single value throughout.
StripeSize must be 2^n (n = 2 to 9)
-f, --force
Proceed with size extension without prompting.
-n, --nofsck
Do not perform fsck before extending filesystem when filesystem requires it. You may need to use --force to proceed with this
option.
-r, --resizefs
Resize underlying filesystem together with the logical volume using fsadm(8).
Examples
"lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size of that logical volume by 54MB on physical volume /dev/sdk3. This is
only possible if /dev/sdk3 is a member of volume group vg01 and there are enough free physical extents in it.
"lvextend /dev/vg01/lvol01 /dev/sdk3" tries to extend the size of that logical volume by the amount of free space on physical volume
/dev/sdk3. This is equivalent to specifying "-l +100%PVS" on the command line.
"lvextend -L+16M vg01/lvol01 /dev/sda:8-9 /dev/sdb:8-9"
tries to extend a logical volume "vg01/lvol01" by 16MB using physical extents /dev/sda:8-9 and /dev/sdb:8-9 for allocation of extents.
