Relax and recover
Hi list, does anyone heard about relax and recover[1], an open source desaster recovery tool for Linux? Its a collection of shell scripts which create a bootable image from a running system. At boot time hard disks are formatted and data restored e.g. from Tivoli Storage Manager. See the demo [2]. The ISO files are not bootable on s390x, but maybe someone here has an idea how to use it on our platform.

run-crons and sa1 looping
Dear list, since we upgraded from SLES9/SLES10 to SLES11 SP1 the first thing I do every morning is to kill -9 some CPU eaters. Either run-crons or sa1 (sysstat) is looping on a CPU.

Re: Missing disk at boot
Well I don't know what I missed doing the LVM manually. But I removed the LVM dasd from fstab so that I could boot cleanly. Then using yast I recreated the LVM vg lv. Reboot and it all works fine. I tried to reproduce the problem and noticed that yast adds 2 symlinks (/etc/init.d/boot.d/K05boot.lvm and /etc/init.d/boot.d/S09boot.lvm) if LVM wasn't used before. Maybe it helps.

Re: Missing disk at boot
Do a find /etc -type f -mtime -1 to see what files have been changed in the last 24 hours, and compare the list of those files, and their contents to what you did manually. I often use backups to find changes: 1. Make a full backup 2. Do the thing 3. Make an incremental backup and see which files are backed up We store two versions of a file in the backup, one active and one inactive. So I can restore the original file and find the changes with diff.

Re: pvmove hangs
IMHO it is not arch or distro specific. It looks exactly like as https://bugzilla.redhat.com/show_bug.cgi?id=193330 and the LVM developers are keen for somebody with a reproducer. Dan, thank you very much for the link. Your tip at comment #10 helped. If I specify each logical volume, pvmove moves all data successfully: pvmove -v /dev/dasdd1 -n lvhome pvmove -v /dev/dasdd1 -n lvusr pvmove -v /dev/dasdd1 -n lvvar ... It seems to avoid a deadlock situation. I will provide the requested informations on the bugtracker.

If I reboot the system it doesn't comes up, because the pvmove is restartet during the boot and the system freezes again. I can rescue the system with a few steps: IPL into CMS, detach a LVM managed minidisk, boot the guest which doesn't comes up (Give root password to login), edit the fstab with ed and delete all mounts with LVM volumes, attach the minidisk again and reboot. The system comes up and pvmove starts to work

VDISK size problem
Hello list, I use SWAPGEN for VDISK. It's defined in the PROFILE.EXEC: 'SWAPGEN 203 3145728' This entry works, and my VDISK has 1,5 GB. If I try to define a larger VDISK an error occurs: Error 91 from CP DEFINE VFB-512 AS 203 BLK 4194304: HCPLNM091E DASD 0203 not defined; vdisk space not available vdisk space not available? I can define five further VDISKs with 3145728! We have got enough space. How can I define larger VDISKs? VDISK SYS- and USERLIM are both infinite.

Re: Network freezes
Sounds like your guest is not getting dispatched. If it's not getting dispatched I couldn't log in and work almost normally (ping, change directories, mount, df...). But I can do so! -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: Network freezes
How much memory do you currently have defined to the guest, and how much real memory is available on the system? zVM: 8 GB + 4 GB Exp. There are two guests with the described problem: guest1# free -m total used free sharedbuffers cached Mem: 995987 8 0 58349 -/+ buffers/cache:578416 Swap: 2047416 1631 guest2# free -m total used free sharedbuffers cached Mem: 995985 9 0 57334 -/+ buffers/cache:593402 Swap: 2047281 1766 All other guests with less workload don't have this problem. If you drastically reduce its memory allocation, things will move much better. I often read this hint on the mailinglist to reduce memory, but what if the application (SAP) needs it? Two days ago my guest2 got stuck because mem and swap was 100% used and it began to kill processes to free memory. I thought I have to add mem and swap... And: it doesn't get stuck. It's alive. I only cannot do any networking with it.

Network freezes
We've got a curious problem here with some linux-guests on a z990 with zVM44 and SLES8, k_deflt-2.4.21-221, Gigabit Ethernet OSA. Sometimes all network connections are going down, e.g. all ssh sessions get lost with timeout etc. A ping doesn't reach the linux. Pings from direct network-neighbours to the linux fail, too. If I log on to the zVM console almost everything looks fine. I can ping it's own IP-address, but not the Gateway's IP-adress or the neighbours. A mount or df hangs when it should list NFS-mounted directories from other servers. If I reboot the linux-guest the problem is gone. Or I can wait a random time (around 20-45 minutes), suddenly the linux answers again. There are no error-messages in /var/log/messages. I have exactly _no_ idea what I can do now. An inconfig eth0 down/up doesn't change anything. I cannot reproduce this error, so I have to wait until it happens the next time. Any hints what I can do when it happens again next time?

Routing Problem
Hi, I've got a problem with my linux-routers. They route between the hipersocket-network-area and the rest of the net. The problem occurs after echo no_router eth0 /proc/qeth on the primary router, the secondary router stops routing and I don't know why. Both eth0-devices of the primary and the secondary router were attached to one OSA. Maybe that's my fault!? I know that this solution is insecure but right now our other OSA is used for other testing-purposes... Suggestions? Greetings, Sebastian Jetzt bei WEB.DE FreeMail anmelden = 1qm Regenwald schuetzen!
