Preferred way to backup


-----BEGIN PGP SIGNED MESSAGE-----

Hi.

Is there any preferred solution to backup a gfs partition?
Can the "dump" command work without problems?
Maybe tar? Or any other command gfs-specific command?
Thanks

recipe for gfs whit parallel scsi and gulm

Hi,

I'm begginer with GFS and i need some helps please.
I've gfs 5.1.0 to evaluate which software license
number is BE-0005-10001015.
I want to set up GFS on cluster of nodes with parallel
SCSI with IP lock server using gulm lock server but
neither of your recipes match with that. Then i'm
attempt create one specific recipe groundoing in yours
recipes in section 5.3(GFS with Fibre Channel and gulm
lock server) and 5.5(GFS with parallel scsi and
LOCK_SWDMEPD) to do why i want, but i have some doubt:
1.Why the pool module is not loaded in recipe 5.5?
2.Using IP-based DMEP, all pooldevices should have a
weight of zero. The same role apply to IP-based GULM?
3.Why the i/o fence daemon are not started in the
nodes in the recipe of section 5.3?

Please, Could you see the file attached with the
description of the recipe and localized questions i'm
trying to create, to give me the feedback if it's
correct.

Other question:
Who is the correct way to stop the gfs before do
reboot or shutdown the nodes?

Thanks for your helps.
Manuela Fortes.

really poor performance on a 2 terabyte gfs


does anybody out there have a configuration with at
least a 2 terabyte filesystem? i am using gfs 5.1 and
in even doing simple things like 'ls -l' it takes
MINUTES to return a result. basically we have a large
ftp site currently running on  an sgi. the same
command
on the same directory structure behaves normally, or
as one would expect it to, on the sgi. on our linux
box, running gfs 5.1, the results take up to two
minutes
to return a listing. thanks.

how do you use gfs


i will eventually have to justify gfs to people. the
system we have in place was purchased by the system
administrator before. through one person on this, i
received a very detailed description of how he was
using gfs. it got me to think how is everyone else
using gfs, what version, and what hardware. i'd like
to know how big the gfs community is.

RE: Any experience with GFS on U*IX?

Ken,
Currently GFS is only for Linux with a port possibility to BSD.  I am
currently deploying a large Linux cluster on IBM XSeries hardware.  I would
jump for joy if Sistina would port to Solaris.

Hi,

This is probably a dumb question, but I'm new to GFS and trying to cobble
together an Open Systems alternative to SANergy and GFS.

Does anyone have experience using GFS with the following clients:

	Sun Solaris
	HP Tru64 UNIX
	SGI IRIX
	IBM AIX
	Cray UNICOS
	HP UX

Thanks in advance,

RE: gfs 5.1, rh 7.3, qlogic 2200, and a brocade

Just some follow-up...

Some storage subsystems insist on having and/or starting at LUN 0, even
though their is no such requirement in the SCSI standards (SAM-2).  Others
do not.

Also, some subsystems require a complete 0..N LUN scheme, i.e. if LUN N
exists, all LUNs 0..N-1 must also exist.  Once again, this is a non-standard
but is (all too) typical of proprietary controllers.

Hi

I've experienced the same problem with SuSE 7.3 and RH 7.3 with my qla2200
connecting to a Compaq HGS80.
At qlogic web site I found SANsurfer, an HBA administration software from
which I can see my LUNs. This tells me that HSG80 and qla2200 are working
well. But, cat /proc/partitions does not show the logical units and
/var/log/messages only shows that qla2200 has discovered the HSG80
controller (LUN 0) but not the other LUNs.
Just yesterday I discovered where the error is: at SCSI support module. It
seems like each LUN discovered tells the kernel wether it needs to continue
