x86_64 reproducible server PANIC with latest kernel
by Kay Diederichs 02 Aug '06

02 Aug '06

Our Tyan VX50 server, which is otherwise stable, can be crashed by a specific user who starts a Java application. Relevant facts are: x86_64 CentOS 4.3 fully updated (but otherwise default config) 8 Dual-Core Opteron 870 (2 GHz), giving 16 cores 32 GB memory (running at DDR333) The panic is reproducible within a couple of minutes. I tried the 2.6.9-42 largesmp kernel from J.Baron's website because it has some fixes, but the result is the same as with 2.6.9-34.0.2-largesmp . The panic is not triggered by memory overcommitment, when the crash occurs, there is still 8GB free memory and the swap space is untouched. This is the start of the dmesg output which I could capture from a "netconsole": NMI Watchdog detected LOCKUP, CPU=6, registers: CPU 6 Modules linked in: vmnet(U) vmmon(U) netconsole netdump ppdev nfs nfsd exportfs lockd nfs_acl md5 ipv6 parport_pc lp parport autofs4 w83627hf i2c_sensor i2c_isa i2c_dev i2c_core sunrpc ipt_REJECT ipt_state ip_conntrack iptable_filter ip_tables dm_mirror dm_mod button battery ac ohci_hcd ehci_hcd tg3 floppy ext3 jbd raid1 raid0 sata_nv libata sd_mod scsi_mod Pid: 16269, comm: java Tainted: PF 2.6.9-42.ELlargesmp RIP: 0010:[<ffffffff8030a9aa>] <ffffffff8030a9aa>{.text.lock.spinlock+46} RSP: 0000:000001032d1a1e08 EFLAGS: 00000086 RAX: 000001032c2e5030 RBX: 00000107fc53dac8 RCX: 0000000000000000 RDX: 000001032d1a1f58 RSI: 000001032d1a1ef8 RDI: 00000107fc53dac8 RBP: 000001032d1a1e78 R08: 0000000000000007 R09: 0000002a95905ac8 R10: 0000002a95905ad6 R11: 0000000000000000 R12: 0000000000000000 R13: 000001032d1a1ef8 R14: 000001032d1a1f58 R15: 000001032c2e5708 FS: 0000000042a7b960(005b) GS:ffffffff804f8000(0000) knlGS:00000000f7e886c0 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000002a95ed2f88 CR3: 00000006fc7a2000 CR4: 00000000000006e0 Process java (pid: 16269, threadinfo 000001032d1a0000, task 000001032c2e5030) Stack: 000001032d1a1f58 ffffffff80142d80 0000000042a78610 000001032d1a1f58 0000000042a78610 0000000000000000 0000002be7877da0 0000000000000042 000001032d1a1ef8 ffffffff8010f6fb Call Trace:<ffffffff80142d80>{get_signal_to_deliver+64} <ffffffff8010f6fb>{do_signal+131} <ffffffff801100b4>{sys_rt_sigreturn+619} <ffffffff80110129>{sys_rt_sigreturn+736} <ffffffff80110902>{retint_signal+62} Code: 83 3b 00 7e f9 e9 91 fd ff ff f3 90 83 3b 00 7e f9 e9 cf fd Kernel panic -

Now, what I've done for my own NAS is to install CentOS 4.3 under Server->Minimal. I create a 6GB partition on one of my 3Ware cards for the OS. Then the rest of the space I use LVM to manage what I need. You'll need to install Samba if you need SMB, but essentially building a NAS is pretty easy. I've reached the stage where I can start from bare metal, and have a 5TB NAS up and running in about 30 mins - after the RAID5 array has finished initializing! :) I looked at OpenFiler as well, but was have difficult times getting it to run on my HW. It would simply lock up while formatting drives - not sure why... Since I really don't need a GUI to manage things, I keep things simple and use CLI for everything. HTH Mark

firefox 1.5.0.5 packages
by Barry Brimer 01 Aug '06

01 Aug '06

I installed the new firefox 1.5.0.5 packages and had a few issues. I had read a similar post on the nahant list. I would doubt that this is a centos-induced problem. The browser crashed when opening the extensions manager and also with a very simple webmail page. I have reverted to the firefox 1.0.8 packages and these problems have disappeared.

01 Aug '06

Hello, I have a Dual boot laptop that is running XP and Centos,i would like to remove the Centos from the laptop. How would i go about doing this since Centos loaded the grub loader onto the MBR i can not just go and delete the Centos part since grub will still be in the MBR thanks Steven "On the side of the software box, in the 'System Requirements' section, it said 'Requires Windows or better'. So I installed Linux."

Connect-Disconnect DSL on commandline
by Timothy Kesten 01 Aug '06

01 Aug '06

Hi Folks, I'm using CentOS 4.3 on my Desktop-Computer. I've been switched from Suse: I'm using for Internet-Connection DSL (Germany). It will be started at boottime. But how can I connect/disconnet this connection without using a GUI during the Computer is runnig . Is there a command(-line-tool)? On Suse there was a program called "cinternet" that fits for this task. An other question: I've running a server in a small Network with Suse 9.0. I want to switch this server to CentOS because of stability and long support. Because CentOS is a "clone" of RHEL I've heared in december 2006 there will be a new version of RHEL. How long will it takes until CentOS is adapted to this new version? Is it recommendable to wait for new CentOS? I dont want setup the server two times in the next 12 month ;-) Thx Timothy

add'l info: x86_64 reproducible server PANIC with latest kernel
by Kay Diederichs 01 Aug '06

01 Aug '06

I forgot to mention that the problem has nothing to do with the kernel being tainted (due to VMware server). I installed VMware server after being faced with the crashes, to give the Java user a "sandbox" which s/he could crash without taking down the real server. Only then I discovered that VMware server has a memory limitation to 3600MB (I guess because it's not a 64bit application). I see exactly the same crash with a non-tainted kernel.

Samba/ldap install script from k12osn perl problems
by Robert Moskowitz 31 Jul '06

31 Jul '06

There has been some very good work by a few people over in k12osn for setting up a SAMBA PDC/BDC environment. Thing is their scripts are for Fedora core 3. There are instructions on how to get things to go step by step instead of use the Fedora-based script, so I gave it a try. Step 1 is to get apt running and everything current. I assumed yum would do instead. step 2 has: *Installing CPAN bundles * Now we need to make sure our perl modules are all there and up to date. We can do this easily by Running perl -MCPAN -e –shell Let it run. Answer “no” when it asks about Manual configuration. Once it stops you'll be at the cpan prompt....type install Bundle::CPAN this will install many perl modules for you. Answer “yes” to any dependency questions. When you get to the question about “libnet”....answer “no”. Once you are finished...hit “enter” to exit....it'll run for a few seconds more and then bring you back to the cpan prompt. For good measure let's type install Net::LDAP (it should be up to date) ======================================= Well I had many messages from the perl -MCPAN and install Bundle::CPAN and the install Net::LDAP just failed. Being how this is rather foreign to me, how do I figure out what really went wrong and how to get it right?
