Hello, I am having some problems setting up GFS 6.0. I have the src rpms, and built them against kernel-2.4.21-15.ELsmp on x86_64. The kernel modules all load, everything seems to build properly. I create the pool device, am able to create the file system as well. However, when I do the mount command (mount -t /dev/pool/pool_gfs01 /gfs01) the machine crashes instantly. lock_gulm seems to be the culprit, however I cannot get any useful information out of the system about why this is happening. No logs, just whammo - the system dies instantly. My platform information is as follows: Rocks 3.1 (based on RHEL WS 3.0) Dual 1.4 opterons Kernel from rpm: kernel-smp-2.4.21-15.EL kernel source from rpm: kernel-source-2.4.21-15.EL GFS: GFS-6.0.0-1.2.src.rpm My dev files look like: /dev/pool: brw------- 2 root root 254, 65 Jul 31 01:12 hopkins_cca brw------- 2 root root 254, 66 Jul 31 01:12 pool_gfs01 Modules are loaded: gfs 261792 0 (unused) lock_gulm 68960 0 (unused) lock_harness 4048 0 [gfs lock_gulm] pool 85760 3 uname -a: Linux frontend-0.public 2.4.21-15.ELsmp #1 SMP Thu Apr 22 00:09:01 EDT 2004 x86_64 x86_64 x86_64 GNU/Linux [root@frontend-0 root]# pool_tool -s Device Pool Label ====== ========== /dev/pool/hopkins_cca <- CCA device -> /dev/pool/pool_gfs01 <- GFS filesystem -> /dev/sda <- partition information -> /dev/sda1 hopkins_cca /dev/sda2 pool_gfs01 And when I do the following mount command: mount -t gfs /dev/pool/pool_gfs01 /gfs01 The system crashes. At the console, there are tons of system calls being listed, and at the bottom of the screen: Code: 39 d0 75 f8 85 c9 74 10 8b 44 24 14 39 d0 74 08 8b 44 24 14 Console Shuts up: pid: 3547, lock_gulmd Not tainted RIP: 0010 So... Any ideas on what may be causing this? This seems to be a supported platform for this tool according to redhat. Has anybody used GFS 6.0 on this kernel rev on x86_64 and if so, how did you get it to work? Other information: HBA: QLogic Corp.
