Urban, I've made some changes related to the way mmap files are handled, can you please check with the latest TLA (glusterfs--mainline--2.4) thanks avati 2007/5/15, Urban Loesch <ul@xxxxxxxx>:
Hi, I have a problem with "mmap" on my GlusterFs test environment and "apt" on Debian. My environment: Hardware: 2 different servers for storage 1 server as client On top of the server I use a virtual server setup (details http://linux-vserver.org). OS: Debian Sarge with self compiled 2.6.19.2 (uname -r 2.6.19.2-vs2.2.0) and latest stable virtual server patch. GlusterFs: latest mainline 2.4 from repository What I'm trying to do: - Create a AFR Mirror over the 2 Servers. - Mount the Volume on Server 3 (Client). - Install on the mounted volume the hole virtual Server with Apache, MySql and so on. So I have a full redundant Virtual Server mirrored over two bricks . After some help from Avati Anand last week the above setup works just fine. I tried out Mysql and it works normally (will make some more tests in the future). But now I have the problem with apt. For example when I try to update the packagelists within the virtual server I get the following error: mastersql:/# apt-get update Get:1 http://security.debian.org etch/updates Release.gpg [189B] ... Hit http://ftp.de.debian.org etch/non-free Packages Fetched 2B in 7s (0B/s) Reading package lists... Error! E: Couldn't make mmap of 12582912 bytes - mmap (19 No such device) W: Unable to munmap E: The package lists or status file could not be parsed or opened. After some googling I found out, that apt uses "memory mapped files" and it seems that apt can't find some device. But I'm not able to find out which device does it can't find. Short description of MMAP: http://www.ecst.csuchico.edu/~beej/guide/ipc/mmap.html Have you any idea what can cause this problem? Without GlusterFs as the underlaying filesystem the problems not occurs. thanks Urban Loesch _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxx http://lists.nongnu.org/mailman/listinfo/gluster-devel
