I even saw a 100-sided die one time. It looked a lot like a large golf ball. Took forever to stop rolling. Jon /snip Dude! You never played Dungeons Dragons? Two 20-sided dice (icosahedra) give you a number between 00 and 99 with an even probability distribution. Picture at

I thought there were some data corruption problems with Reiser on s390. Is my impression mistaken? Jon snip Reiserfs is more popular, because it is the default in SuSE. We've observed a fair number of cases where reiserfs fails at very high I/O rates, so we tend to use ext3 in places where we

Thanks to those of you who replied on this issue. I was under the (mistaken) impressions that I had already done both the mkinitrd and zipl steps, but I apparently forgot the mkinitrd. Mea culpa. Thanks again, Jon -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED]

Logical volume inactive at IPL

2006-04-18 Thread Jon Brock
I'm sure I have seen this question answered before, but I can't find it on the archives. I have a linux guest (SLES 8) under VM 5.1 which fails to bring its logical volumes online when it is IPLed. After every boot, I have to go into linux and issue a vgscan command, followed by an lvchange

The shutdown/snapshot/restart method is what we use -- quick, solid, and relatively painless. Still, I would prefer not to have to do it that way, though. Doesn't linux maintain I/O performance heuristics that are lost at shutdown time? Jon snip Linux has data in its internal buffer cache

Thanks for the reply, Jay, and you just answered the follow-up question I was going to ask; namely, is it possible to dynamically grow a striped LV. Guess not. I'll give the alternate format of the lvcreate command a try. Thanks, Jon snip Try this lvcreate command instead: lvcreate

Are any of you out there running linux under z/VM with a large guest image? That is, do you have any systems defined in the directory with a size greater than, say, 1500MB or so? I'm interested in any large guests but especially production ones. If so, what sort of tuning problems have you
