Re: [CentOS] Grub fallback problem
From: Matthias Blankenhaus matthiasblankenh...@yahoo.com The problem is that the fallback does not work for me. For instance, if I specify on purpose a wrong root device with the NEW OS, e.g. root=/dev/sda3, then the kernel panics and reboots properly after 5 sec. However, grub then attempts to boot the NEW OS all over again. The same is true when I fully boot NEW OS with the right root device and then panic the kernel on purpose. Now, I have read somewhere that grub requires a default file to get the savedefault feature working. However, I could neither find the 'savedefault' command nor the grub default file under /boot/grub or anywhere else. One more thing, when I choose the boot title manually then grub seems to remember my last choice. In other words, grub is preserving my last choice from a previous boot. Not sure if you already read this: http://www.gnu.org/software/grub/manual/html_node/Booting-fallback-systems.html#Booting-fallback-systems JD ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] 'Missing end of line'

The headers don't suggest client origin, to me). I've checked the logrotate.conf script and it looks OK to the untrained eye. It ends with an empty line. Any clue as to what I should be checking? If you modified it, check maybe if you don't miss a '}' somewhere. If you did not, maybe try 'rpm -V logrotate' to see it if is the original.

Re: [CentOS] {SOLVED} Re: OT: SMART warning on hard drive, same warning for 2 1 /2 years
From: Lanny Marcus lmmailingli...@gmail.com Thanks to everyone who replied. As Mark (MHR) wrote, I too was skeptical of the SMART warnings from the BIOS and when I checked on the Compaq Support site, a couple of years ago, I was told the Compaq BIOS is very sensitive and there are a lot of false warnings. However, after checking the bad hard drive with smartctl yesterday, I am a believer in SMART warnings From what I understand, there is a max number of errors allowed before the warnings appear. This max number is arbitrary I guess. In the past, HP bioses had this max number apparently set too low. With firmware updates, the max was raised. So, while you were warned too early, your disk finaly reached the real max. JD ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] What is writing to my filesystem

Re: [CentOS] TIME_WAITs...
If I make 1 rapid connections/selects/deconnections to mysql on this server, I get like 1 TW after around 3000, another TW around 6000 and another TW around 9000... That makes 3 TWs only. And they last 60 seconds... In your testing is the source IP the same for all with just different source port? Or are you varying your source IP as well? I don't know what spoofing smarts are in the kernel to detect SYN/ACK attacks. The source was the same on both servers (the one with thousands of TWs and the one with 3 TWs). Are you running Shorewall or any similar tool that will detect SYN/ACK attacks and might be seeing this 'test' as an attack to limit? No shorewall and no iptables rules. When I googled for it, many people were pointing to the tcp_fin_timeout value ... Is it really related to TWs? Well, yes. How long do you let a TW sit around waiting for a proper FIN or even a RST? Read the TCP RFC as to why there is a TW in the state machine. Boy has it been years since I cracked that one open... I read about the connection handshake but I do not really see why setting the FIN_WAIT timeout would also set the TIME_WAIT timeout to the same value... And I tried to set it at 30s and TWs did still last 60s. Thx, JD ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] TIME_WAITs...
I spent a bunch of time researching TIME_WAIT on linux and didn't find much useful information. There's a couple kernel parameters to change the settings though the only docs for them that I could find say don't touch them unless you REALLY know what your doing Only things I found are the hardcoded values in include/net/tcp.h: #define TCP_TIMEWAIT_LEN (60*HZ) /* how long to wait to destroy TIME-WAIT * state, about 60 seconds */ #define TCP_FIN_TIMEOUT TCP_TIMEWAIT_LEN /* BSD style FIN_WAIT2 deadlock breaker. * It used to be 3min, new value is 60sec, * to combine FIN-WAIT-2 timeout with * TIME-WAIT timer. */ Our issue is on the LAN side: front servers connecting to the dbs. So I wonder if 60s is not too long for the delayed packets problem, when the sources and the targets are one gigabit switch away... The app that runs on that box is very high volume, so we get a large number of TIME_WAITs, during performance testing on a dual proc quad core we can get up to 63,000 of them. Hum... I think I just understood why I cap around 14,000 in my tests... cat /proc/sys/net/ipv4/ip_local_port_range 32768 61000 (61000-32768)/2 = 14116 Could that be it? So IMO don't worry about time waits unless your seriously in the 10s of thousands, at which point you may want to think about optimizing the traffic flow to your systems like we did with our load balancers. We already use LVS+keepalived and it seems to work fine so far (except when I tested 1.1.16 ^_^). Thx, JD ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] TIME_WAITs...
Hi, I was asked to check some TIME_WAITs problems (my boss thinks there should almost never be any) and I bumped into something strange... All of our servers have apparently normal (in my opinion) 60s TIME_WAITs (even if it strangely caps around 14000 in my tests)... But one of them behaves differently (and my boss thinks it is the normal behavior). If I make 1 rapid connections/selects/deconnections to mysql on this server, I get like 1 TW after around 3000, another TW around 6000 and another TW around 9000... That makes 3 TWs only. And they last 60 seconds... I am told this server was not really setup differently (no custom kernel). All servers are CentOS 5.2, kernels 2.6.18-92.1.[22|10].el5. I compared the values in sysctl.conf and /proc/sys/net/ipv4/* and nothing different. So, am I correct in thinking that seeing thousands TWs when there was a burst of thousands connections is normal? Any idea why so few TWs on this server? Any conf file I should check? # cat /proc/sys/net/ipv4/tcp_fin_timeout 60 # cat /proc/sys/net/ipv4/tcp_max_tw_buckets 18 # cat /proc/sys/net/ipv4/tcp_tw_recycle 0 # cat /proc/sys/net/ipv4/tcp_tw_reuse 0 When I googled for it, many people were pointing to the tcp_fin_timeout value ...

Re: [CentOS] Keepalive...
I changed my apparently faulty nic, but it does not change anything... I can reproduce this: I bring down keepalived on lvs1. Keepalived on lvs2 says it switched to MASTER but does nothing. 2 possibilities: - If no VIP, as soon as I manualy add the VIP, everything is unlocked and he forward the requests... - If there is a VIP, a ifdown+ifup of the interface linked to the web servers will unlock keepalived. I bring up keepalived on lvs1, and it does not setup the VIP. On lvs2, it says: removing protocol VIPs, but the VIP is still there. A ifdown+ifup on lvs2 of the interface linked to the web servers will unlock keepalived on lvs1... And, from times to times, it will work as expected... One thing I really do not understand is why restarting the nic linked to the webservers will unlock the vrrp on the other nic... The only thing that almost never work is the service checks... After one check, or a few at best, they just disapear... JD ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Restarted them on monday and... it did not work anymore. Tried 1.1.15 as suggested, same. So, I installed the keepalived-1.1.16-1.el5.hrb rpm David kindly built. And, not really better. My config more or less work... More 'less' than 'more' sadly... I have many random problems and weird behaviors, that fix themselves after a few restarts/reboots, without changing anything in my conf. And they will be back at the next restart... Once, it is the vrrp stuff that do not seem to work. I say seem because, even if tcpdump does not show any vrrp packets (it does other times), sometimes the backup catches the master that was brought down and switches to master state. And, at other times, both detects nothing at all... A few restarts and it works again until next failure. And at other times, I can see the packets... There were times when both would be master... Another time, keepalive does not seem to check the webservers as regularly as other times. I say again seem because, while the accesslog of my webserver does not display any recent entry from keepalive (hash) checks, keepalive still detects that one web server was brought down and that it temporarly removes it from its list... And I see nothing in keepalived logs about this... Except once in a while. By example, right now lvs1 is master, and I see only lvs2 checks in my web logs. But if I bring down web1, lvs1 catches it and removes it until I bring it back up... Another time, the arp resolution on my client for the VIP is incomplete. Fixed after a few restarts. Many times, the master gets stuck on VRRP sockpool. Each time there is a problem, I checked and both my web servers are accessible from the 2 lvs servers and from outside through the exit IPs (192.168.16.[228|229]). Also, when I use service restart, it will fail once out of 3 times with Keepalived: daemon is already running... Am I the only one having all these unstabilities?

From: bruce bedoug...@earthlink.net goat a bunch of files in different dirs.. the files might have spaces 1foo_ aa_bb_cc.dog 2foo_aa__cc.dog 3foo_aa_bb _ccc.dog 4foo_aa_bb_cc.dog 5foo_aa_bb_cc.dog 6foo_aa_bb_cc.dog i'm trying to figure out how i can do a complete list of all files with *foo*dog so i get the files with spaces and underlines... i thought simply doing somehting like ls '*foo_*.dog' and surrounding the filename with single quotes would work.. but it doesn't. thoughts/pointers/etc... If you quote, it disables the completion... $ echo *foo_*.dog 2foo_aa__cc.dog 4foo_aa_bb_cc.dog 5foo_aa_bb_cc.dog 6foo_aa_bb_cc.dog $ echo '*foo_*.dog' *foo_*.dog JD ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Keepalive...
Hi,
I've been trying to setup keepalive (vrrp) with LVS in direct routing on Centos
5 and I am stuck...
Installed ipvsadm from the repo (had to touch /etc/sysconfig/ipvsadm because it
complained it was missing)
Compiled keepalived-1.1.16.tar.gz
Test setup:
main switch (192.168.16.0/20)
|
eth0: 192.168.28.[226|227]
VIP=192.168.16.123
2 lvs/keepalived servers
eth1: 10.0.0.[1|2]
|
test switch (10.0.0.0/8)
|
10.0.0.[11|12]
VIP=192.168.16.123
test servers (real servers)
192.168.16.[228|229]
|
back to main switch
But let's focus on the 2 lvs servers...
keepalived.conf:
global_defs {
notification_email {
r...@localhost
}
notification_email_from keepali...@lvs1.iper
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id LVS_MASTER ### BACKUP on the backup ###
}
vrrp_instance VI_1 {
state MASTER ### BACKUP on the backup ###
interface eth0
lvs_sync_daemon_interface eth1
virtual_router_id 51
priority 100 ### 99 on the backup ###
advert_int 1
smtp_alert
virtual_ipaddress {
192.168.16.123
}
}
virtual_server 192.168.16.123 80 {
delay_loop 6
lb_algo rr
lb_kind DR
persistence_timeout 50
protocol TCP
real_server 10.0.0.11 80 {

}
real_server 10.0.0.12 80 {

}

}
/var/log/messages:

Feb 20 15:01:09 lvs1 Keepalived_vrrp: VRRP sockpool: [ifindex(2), proto(112),

And that's it... no VIP showing up... no error message...
Looking at the (outdated) log example from the keepalived doc, I seem to miss
all the parsing of the configuration.
A bit like if it was stuck in the vrrp child...
On the backup, I get these extra:

Suddenly, I went a bit further...
I saw a different (from the outdated doc) config on the web and tried it
succesfully:
virtual_ipaddress {
192.168.16.123/32 brd 192.168.31.255 scope global
}
And get these extra bits:

inet6 fe80::204:23ff:fe9e:f374/64 scope link
valid_lft forever preferred_lft forever
But not sure both lvs are talking vrrp to each other; tcpdump does not
intercept anything...

Re: [CentOS] Keepalive...
From: Tim Verhoeven tim.verhoeven...@gmail.com Install keepalived from rpmforge instead of compiling your own. Because mostlikely your build of keepalived is without LVS support. (Check the output of the ./configure command to verify). I've always used the rpmforge package and it works for me. Regards, Tim P.S. : Dag, your keepalived package is a bit outdated. Could you update it ? Bingo! I did not see that it was not finding the kernel headers... ../configure checking for kernel version... 0.0.0 configure: WARNING: Cannot determine Linux Kernel version. I created a linux symlink and it worked out. Tcpdump reports the VRRP mcasts. And I can browse my web server through my VIP Thx guys! Now, gonna test the failover and the sorry server...

Re: [CentOS] USB Memory Key not recognized
From: James B. Byrne byrn...@harte-lyne.ca I have a USB meory key (Kingston) that I formally used with a CentOS-5.2 (32bit) system. When I plug it into a connector slot the light on the key comes on but there are no entries created in /media and no entries made to the /var/log/messages file. Maybe not enough power... Can you try another USB slot? Do you have a powered USB hub to try with it? JD ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
