Operating Systems AIX Questions about setting up GPFS Post 302733169 by jstnobdy on Monday 19th of November 2012 11:02:25 PM

Hello!

To your first question, GPFS is a full device allocation, therefore, anything you wish to allocate will be consumed as an NSD.

Regarding your second question, yes, that disk is more than likely empty and therefore can be used for GPFS.

Finally, GPFS can run on one node (a single node quorum) and can have additional nodes added to it later. Make sure you have good time synchronization (xntpd) and decent performing disk storage.

Best regards,
jstnobdy

One more thing, GPFS is pretty tolerant, just make sure you define "dataOnly" and "metadataOnly" disks when you create your NSDs (mmcrnsd). In this case, allocate 'x'-amount of storage for dataOnly NSDs and a relatively small disk for metadataOnly.

Good luck. If you have any questions, let me know.

local-filesystems(7)					 Miscellaneous Information Manual				      local-filesystems(7)

NAME

       local-filesystems - event signalling that local filesystems have been mounted

SYNOPSIS

       local-filesystems [ENV]...

DESCRIPTION

       The  local-filesystems  event  is generated by the mountall(8) daemon after it has mounted all local filesystems listed in fstab(5).  moun-
       tall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with  other
       activity.

       This event is typically used by services that must be started in order for remote filesystems, if any, to be activated.	Remember that some
       users may not consider it wrong to place /usr on a remote filesystem.  For most normal services the filesystem(7) event is sufficient.

       This event will never occur before the virtual-filesystems(7) event.

EXAMPLE

       A service that wishes to be running once local filesystems are mounted might use:

	      start on local-filesystems

SEE ALSO

       mounting(7) mounted(7) virtual-filesystems(7) remote-filesystems(7) all-swaps(7) filesystem(7)
