[Gluster-devel] GlusterFS core dump (v1.2.3)

[Ton van Rosmalen]

    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!

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.

Regards,

Ton
