I want to increase the size of /tmp by 1GB
I know that the command is
chfs -a size=+1G /tmp
But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks.
Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ?
Please advise. (1 Reply)
Hi,
For a particular set of files, am trying to check if they are writable. i.e., checking whether they are having permissions greater than 755.
Am able to check this using the statement:
"if (os.path.isfile(FILE_PATH) and (os.stat(FILE_PATH).st_mode & 0777) == 0777):"
But the problem here... (0 Replies)

lvmerge(1M)lvmerge(1M)NAME
lvmerge - merge two LVM logical volumes into one logical volume
SYNOPSIS
autobackup] copy_lv_path master_lv_path
Remarks
This command requires the installation of the optional HP MirrorDisk/UX software, which is not included in the standard HP-UX operating
system.
DESCRIPTION
The command merges two logical volumes of the same size. The copy_lv_path is added as a mirrored copy of master_lv_path and only the mas-
ter_lv_path logical volume is retained. The number of mirrored copies of the master_lv_path is increased by the number of copies in the
copy_lv_path. Either copy_lv_path or master_lv_path must be an unmirrored logical volume.
Data previously contained in the copy_lv_path will be resynchronized using the data in the master_lv_path. All new data on the
copy_lv_path will be destroyed and the copy_lv_path logical volume will be removed.
By default, completes after all the extents are resynchronized. When run with the option, if there is no bitmap (see below), returns with-
out resynchronizing the remaining logical volume. Using the option may affect data high availability as extents may remain stale. Use or
to synchronize the mirrors.
The normal usage for this command is to merge previously mirrored logical volumes that have been split using the command. However, the two
logical volumes are not required to have been the result of a previous operation.
NOTE: When a mirrored logical volume of a non-shared volume group is split into two logical volumes using a bitmap is stored that keeps
track of all writes to either logical volume in the split pair. If the volume group was shared at the time of the split, no bitmap was
created. When the two logical volumes are subsequently merged using the bitmap is used to decide which areas of copy_lv_path need to be
resynchronized with the master_lv_path. This bitmap remains in existence until one of the following conditions occurs:
o The merge is completed.
o One of the logical volumes is extended, reduced, or split again.
o The volume group is deactivated, or cross-activated to shared mode (see vgchange(1M)).
o The system is rebooted.
If there is no bitmap available, all the physical extents from the copy_lv_path are marked stale. If there is a bitmap available, the
option is ignored.
Options and Arguments
recognizes the following options and arguments:
copy_lv_path The block device path name of a logical volume that will be removed.
master_lv_path The block device path name of a logical volume that will remain.
Set automatic backup for this invocation of this command.
autobackup can have one of the following values:
Automatically back up configuration changes made to the logical volume.
This is the default.
After this command executes, the command (see vgcfgbackup(1M)) is executed for the volume group to which
the logical volume belongs.
Do not back up configuration changes this time.
If there is no bitmap, do not synchronize the
new mirrors in the master_lv_path after the merge. Using the option may affect data high availability as extents
may remain stale. Use or to synchronize the mirrors.
Shared Volume Group Considerations
For volume group version 1.0 and 2.0, cannot be used if the volume group is activated in shared mode. For volume groups version 2.1 (or
higher), can be performed when activated in either shared, exclusive, or standalone mode.
Note that the daemon must be running on all the nodes sharing a volume group activated in shared mode. See lvmpud(1M).
When a node wants to share the volume group, the user must first execute a if logical volumes were merged at the time the volume group was
not activated on that node.
LVM shared mode is currently only available in Serviceguard clusters.
EXTERNAL INFLUENCES
Environment Variables
determines the language in which messages are displayed.
If is not specified or is null, it defaults to "C" (see lang(5)).
If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).
EXAMPLES
Merge with Data in will be overwritten by and will be removed.
Merge with Data in will be overwritten by and will be removed. If the bitmap does not exist, then mark all extents associated with as
stale and complete without resynchronizing.
WARNINGS
does not check to guarantee that the allocation policy of master_lv_path is preserved after the merge.
