Hello, I need to test whether our product will work with GPFS filesystems and I have some questions regarding the setup:
1. Do I need to dedicate an entire hard disk if I want to have GPFS on it? Or can I somehow split a disk into 2 virtual disks, and only use 1 for gpfs?
2. If lspv returns "none" that means the disk is connected but has not been allocated, and thus available for use in GPFS setup?
Example (hdisk3):
3. Do I have to have a second node in order to create a cluster and create a gpfs on that cluster? Or can I start with one node (just to test functionality) and add a second node later? (basically, can I use that one system above with hdisk3 available to test gpfs on its own?)
I have a piece of equipment, a Baytech RPC-3, that I need to communicate with through the com port.
I normally use this equipment at home and am able to connect to it without problems using FC5 and minicom; I brought the equipment into work and cannot get my pc, using Suse 10 and minicom to... (0 Replies)

Hi,
I have a running GPFS cluster. For one every mountpoint that i have created i have one disk assigned to it. That disk is converted to an NSD and is a part of the GPFS Cluster.
Now i have a new disk and there is this requirement to add it to the GPFS cluster, such that this becomes an NSD.... (1 Reply)

WREN(3) Library Functions Manual WREN(3)NAME
wren, ata - hard disk interface
SYNOPSIS
bind #H[drive] /dev
bind #w[target[.lun]] /dev
/dev/hd0disk
/dev/hd0partition
/dev/sd0disk
/dev/sd0partition
...
DESCRIPTION
The hard disk interfaces (wren, #w, is a SCSI disk; ata, #H, is an IDE or ATA disk) serve a one-level directory giving access to the hard
disk partitions. The parameter to attach defines the numerical SCSI target and logical unit number or the IDE drive number to access.
Both default to zero.
Each partition name is prefixed by hd and the numeric drive identifier. The partition always exists and covers the entire disk. The size
of each partition as reported by stat(2) is the number of bytes in the partition, so the size of is the size of the entire disk.
The partition also always exists; it is the last block on the disk for SCSI, second to last for IDE. If it contains valid partition data,
those partitions will be visible as well. Every time the device is bound, the partitions are updated to reflect any changes in the parti-
tion file.
The format of the partition file is the string
plan9 partitions
on a line, followed by partition specifications, one per line, consisting of a name and textual strings for the block start and limit for
each partition on the disk.
The program prep(8) writes the partition table for the disk; its use is preferred to writing it by hand.
