I think something's up - I have just uninstalled 1.2.3 on each node, then obtained & built glusterfs--mainline--2.4; looks like you need to run autogen.sh to produce the "configure" script? Did that, installed... now I'm not getting any directories under my glusterfs mount, apart from a single (and empty) "/home". So I have: /media/glusterfs => gluster FS mount point ls -al /media/glusterfs gives: total 24 drwxr-xr-x 3 root root 4096 May 30 14:57 . drwxr-xr-x 3 root root 4096 May 11 17:32 .. drwxr-xr-x 4 root root 4096 Jun 11 13:46 home But, ls -al /media/glusterfs/home gives: total 0 Rather worrying. However, if I "cd" to a known directory, it works. This dir is also empty. If I "cat" a known file, it's there! Wierd. Log from client just shows "stat-prefetch:flush on: /" 3 times after initial handshake success of servers... I've turned off prefetch caching on the client - no difference. :o( Any idea what could have caused this?

I checked with glusterfs--mainline--2.4 and it shows the same behaviour in my set-up. My VIM version is 7.0.109 (on FC6). I must admit I hadn't tested the permissions yet a reported by Ian. I just checked and mode 0777 gives me a core dump as well. In fact, starting vi with a non-existing file dumps core. Testing with vi(m) further. vi -R <file> - works ok vi -n <file> - works ok write file - core dump It looks like any write command from vi(m) crashes GlusterFS. I checked for the extended attributes as you requested and it said that a selinux-attribute existed on the file(s). I disabled SELinux, deleted all files from the volume and copied them again. Now it works for me! I can edit any file without problems. I guess these selinux-attributes aren't ready yet. Thanks Ton Anand Avati schreef: Can you confirm that this still happens with a tla checkout from 'glusterfs--mainline--2.4' ? we have tested vim to be working. which version of vi have you tried with? also is there a confirmed pattern in the file permission/ownership which is causing this? since the coredump seems to be in unify_getxattr_cbk, can you also check if the file has any extended attributes from the backend fs? thanks! avati 2007/6/23, Ton van Rosmalen <ton@xxxxxxxxxx>: --- original message copied from archive --- Hi there, I get a (rather odd) repeatable bug; if I have a file with permissions -rw-r--r-- (644), and edit it using "vi", I get: E297: Write error in swap file E207: Can't delete backup file E138: Can't write viminfo file /home/scmijg/.viminfo! Next thing you know, glusterfs has core dumped. I've run it in non-daemon mode, and "DEBUG" level - no messages, apart from along the lines of "glibc detected" and "free(): invalid next size (fast)" I dropped the core into gdb, ran a backtrace and it listed "unify_getxattr_cbk" in "unify.so" as the culprit. Looks like pointer corruption? The config is 4 hosts, all hosting their local HDs apart from 1 machine which is hosting an external (USB) drive in addition. Everything running RHEL, all machines AMD Opteron dual-core... Anyone else had this trouble? Otherwise, with other access, Gluster seems OK... Very odd. Say, using "vi" with a file permissions of "-rwxr-xr-x" works fine... Thanks for any help! Ian ----------------- Hi Ian, I've got the same problem. I tested with v1.2.3 about 3 months ago and re-tested with 1.3.0-pre4 this week. My config is running on "VM-Ware Linux-FC6" virtual machines. I've created 3 servers and one client. Normal copy-operations work beautiful. Using vi leads to the same problems as you're experiencing. For me this is a show-stopper. Basic file-editing is a must for me. I've got no suggestion for a solution. Should I find something I'll post it to the list.
