I was going to knowledge base for your post, and I am planning to use gfs2 filesystem for clustering mysql database. after going through this documentation broadcast mode is not suitable mode for GFS2 ? so what will be alternate mode to configuring filesystem.
Thanks
We run two p5 nodes running AIX 5L in a cluster mode (HACMP), both the nodes share external disk arrays. Only the primary node can access the shared disks at a given point of time.
We are in the process of adding two new disks to the disk arrays so as to make them available to the existing... (3 Replies)
Hello,
I have a quick question regarding POWER HA ( HACMP ) 5.5 ;
I have four ethernet adapters
en0
en1
en2
en3
en0 is configured as BOOT_IP with IP address
all other ethernet adapters are empty en1 / en2 / en3
so when I configure the service IP and start HACMP , the service IP... (2 Replies)
Hi,
I have a IBM Power series machine that has 2 VIOs and hosting 20 LPARS.
I have two LPARs on which GPFS is configured (4-5 disks)
Now these two LPARs need to be configured for HACMP (PowerHA) as well.
What is recommended? Is it possible that HACMP can be done on this config or do i... (1 Reply)

Hi everyone. Our professor in Operating Systems gave us a research work about the Heart OS and Love OS. We were told that they were old operating systems from UNIX but I couldn't find any information about them from google. I hope someone here could point me to the right direction. Thanks! (7 Replies)

gfs2_grow
gfs2_grow(8) System Manager's Manual gfs2_grow(8)NAME
gfs2_grow - Expand a GFS2 filesystem
SYNOPSIS
gfs2_grow [OPTION]... <DEVICE|MOUNTPOINT>...
DESCRIPTION
gfs2_grow is used to expand a GFS2 filesystem after the device upon which the filesystem resides has also been expanded. By running
gfs2_grow on a GFS2 filesystem, you are requesting that any spare space between the current end of the filesystem and the end of the device
is filled with a newly initialized GFS2 filesystem extension. When this operation is complete, the resource group index for the filesystem
is updated so that all nodes in the cluster can use the extra storage space that has been added.
You may only run gfs2_grow on a mounted filesystem; expansion of unmounted filesystems is not supported. You only need to run gfs2_grow on
one node in the cluster. All the other nodes will see the expansion has occurred and automatically start to use the newly available space.
You must be superuser to execute gfs2_grow. The gfs2_grow tool tries to prevent you from corrupting your filesystem by checking as many of
the likely problems as it can. When expanding a filesystem, only the last step of updating the resource index affects the currently
mounted filesystem and so failure part way through the expansion process should leave your filesystem in its original unexpanded state.
You can run gfs2_grow with the -T flag to get a display of the current state of a mounted GFS2 filesystem.
The gfs2_grow tool uses the resource group (RG) size that was originally calculated when mkfs.gfs2 was done. This allows tools like
fsck.gfs2 to better ensure the integrity of the file system. Since the new free space often does not lie on even boundaries based on that
RG size, there may be some unused space on the device after gfs2_grow is run.
OPTIONS -D Print out debugging information about the filesystem layout.
-h Prints out a short usage message and exits.
-q Be quiet. Don't print anything.
-T Test. Do all calculations, but do not write any data to the disk and do not expand the filesystem. This is used to discover what the
tool would have done were it run without this flag.
-V Version. Print out version information, then exit.
BUGS
There is no way to shrink a GFS2 filesystem.
