Hello, I am using vserver approx. 2 years for hosting almost all my services (web, mail, application services) A half year ago I changed my main servers to AMD Athlon 64 Processors (3700+). With the host operating system I stayed at 32-bit. I always used lvm2 with reiserfs and with the change I also switched to drbd to mirror the lvm-partitions to a slave servers for the important vservers running.
Since the switch to this configuration the stability is not optimal. Troubles occur in average 1 time a month. Which is not OK, but I accepted it. But yesterday and the day before yesterday during night there were troubles on 2 machines within 10 minutes. What happens? The procedure is allways the same. I monitor the loadavg of all vservers. Here is a table of the loadavg for the host and 1 guest. seconds loadavg_guest loadavg_host 0 0.8 0.25 30 3.3 10.77 60 7.5 20.6 90 11.8 30.4 120 15.7 39 150 16.6 41 ... (increase about 2 in 30 seconds) The other guest on the machines are not affected and worked well. The affected guest had high timeouts with http-connections. I could not enter the affected guest with vserver ... enter. vserver ... stop did not work. vkill did also not work. (I always had to reboot per hardware-reset.) The troubles were always during night hours (with 2 exceptions) where the load on the servers is minimal. Here are the program versions I use Linux version 2.6.17.13-vs2.0.2.1 (gcc-Version 3.3.5 (Debian 1:3.3.5-13)) Debian sarge on the host. Most guest are also sarge, some are gentoo, some are ubuntu 6.06 drbd-0.7.21 util-vserver-0.30.210 kernel / drbd and util-vserver is self-compiled, all other packages (incl. lvm2) are from debian sarge main Does anyone have an idea, what's problem? I don't want to wake up every night per sms. Walter _______________________________________________ Vserver mailing list [email protected] http://list.linux-vserver.org/mailman/listinfo/vserver
