Linux File system under VM
First I am installing SLES 10 SP 2 Linux on z/VM 5.4 When Setting up CKD DASD for Linux on z/VM it asks about using DIAG on the Activated DASD. Was this the Older method for accessing CKD DASD? What is the best Linux File system to use under z/VM. Ext2, ext3, Reiserfs? Larry Davis VM Capability HP Enterprise Services Tel: +1 813 394 4240 E-mail: larry.dav...@hp.commailto:larry.dav...@hp.com
Re: Linux File system under VM
I'd say in the order ext3,ext 2, and I wouldn't even consider reiserfs Mace -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Davis, Larry (National VM/VSE Capability) Sent: Thursday, August 19, 2010 10:29 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Linux File system under VM First I am installing SLES 10 SP 2 Linux on z/VM 5.4 When Setting up CKD DASD for Linux on z/VM it asks about using DIAG on the Activated DASD.

Re: Linux File system under VM
Why not SP3? Save yourself some work later. Or even better - 11 SP1. Ext3 will be the default in 11. It's worked fine for us. I don't think you'd want to use ext2 and lose the journaling. Reiser has had issues in the past ( I think it ate at least one persons files) and there is uncertainty about its future.

Re: Linux File system under VM
Mace is right. Use EXT3 for most things. Use EXT2 for things which will ever be shared. (RO) I also like to use EXT2 for things which don't (or shouldn't) change much, if only because they MIGHT get shared or mounted RO at some later time. The journalling on EXT3 is annoying when you try to go RO. It still wants to replay. Last time I tried (which was recent and was with a very current Linux), I had to use LDL for DIAG to work. LDL is an older layout where the CKD disk is blocked uniformly. I see no reason why CDL will ever work with DIAG. (And part of me hopes it never does. I have an affinity for uniformity and interoperability.) But the IBMers who own that code would have to speak about that future. Near term, DIAG requires LDL. -- R; On Thu, Aug 19, 2010 at 10:34, Macioce, Larry larry.maci...@com.state.oh.us wrote: I'd say in the order ext3,ext 2, and I wouldn't even consider reiserfs Mace -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Davis, Larry (National VM/VSE Capability) Sent: Thursday, August 19, 2010 10:29 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Linux File system under VM First I am installing SLES 10 SP 2 Linux on z/VM 5.4 When Setting up CKD DASD for Linux on z/VM it asks about using DIAG on the Activated DASD.

Re: Linux File system under VM
I have a Novell starter system and have not learned to upgrade it to SP3 or to a whole new release yet. I am in my beginning stages of the process of learning an growing in this area.
