Re: [U2] Red Hat Enterprise Linux 64 bit and Universe 11.1.4 - Experiences?
I believe with EXT4, JFS, or XFS filesystems you can expand them only - while it is mounted. However if you are running RHEL 5 with EXT3, then you have to unmount the partition before you expand. JFS is of course what AIX uses. You can use JFS in Linux, if you set your filesystems up that way originally. I also assume you are using LVM along with a filesystem to manage things... See these notes: http://en.gentoo-wiki.com/wiki/LVM http://tldp.org/HOWTO/LVM-HOWTO/extendlv.html http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/ext4grow.html By the way, I've always thought Gentoo and Ubuntu had great documentation. Red Hat is getting better... In this case, the filesystem and lvm2 utilities should be 99% the same across all Linux distro's, so you can find out what you need to know on Gentoo or Ubuntu docs, even though its RHEL. That is not always the case... As far as the cost goes... you are probably right, since, I don't have the guts to not pay for Linux support and just download CentOS. http://www.centos.org/ However, for us, its more a matter of flexibility and standardization. I have Linux machines (mainly Ubuntu) doing critical business functions already, and if I can have one less operating system to worry about, thats less headache for me. Plus its way cheaper for me to set up a development machine on the fly on my workstation using CentOS. Its nigh impossible to do that with AIX. AIX is great, until you need to use an open source piece of software, then things get tricky. The best answer I found to that problem was this: http://pware.hvcc.edu/ But its maintained by a fellow at a college university, and if he ever gets sick of doing that... then I'm stuck with going through rpm hell.

With RedHat 5, LVM EXT3 filesystems, you can do online resizing. First, you need to increase the size of the logical volume with lvextend. Then you need to resize the filesystem with resize2fs.

Re: [U2] Red Hat Enterprise Linux 64 bit and Universe 11.1.4 - Experiences?
I work with both RHEL AIX, and I'm not sure that you save a whole bunch of money by going Linux anymore. I won't p0ut [AD/} in here, because I'm not a vendor, nor do I have a business relationship with one (anymore). But I was recently investigating making this same move, and my IBM vendor proposed replacing my 2 p570's (4 LPARS each) with a Blade H center, populated with 2 PS701 Blades, for a little under $75K, including 3-year hardwarew warranty 3 year AIX software 24x7 4Hr onsite maintenance. Additional Power blades were $14K, but wintel blades could be had for about $7K each, fitting in the same enclosure. Membership for a comparable RH installation over 3 years was about that same $75K, before you even buy hardware. Of course, you can go without software support on linux, but you'd better be very good at it, especially if your implementation is at all non-standard (um, U2). I also note that one of the most common sysadmin procedures I execute is expanding file systems as data footprints grow. On AIX, I allocate the storage, do a cfgmgr, then issue the appropriate chfs command. In Linux, to expand a file system means taking the volume offline: downtime. P.S.: If I'm wrong about that, please tell me how to do it, thanks.

Hi John, I think you will find it to be a positive move, both technically and financially! Recently I have done a fair bit of testing for a customer who are going to be migrating to 64 Bit Red Hat from a non-AIX variant of Unix and I cannot say I stumbled across any big issues. I was using previous versions of 11.1 for the tests. Do plenty of trials and tests to identify any potential issues, and I am pretty confident you will report back with positive news.

Has anyone had any experiences/challenges running Universe 11.1.4 on Red Hat Enterprise 6 - 64bit? I'm guessing I may get crickets on this one, since accroding to U2 Techconnect, 11.1.4 has only been out about a week... https://u2tc.rocketsoftware.com/buildmatrix.asp Kudos to Rocket for getting it to run on RHEL 6. I'm just scared if I go with RHEL 5, then I'll be in the obsolescence boat two years from now. ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
