Hi GlusterFS-Team,
first thank you for this great piece of software!
I try glusterfs for testing at the moment on 9 servers and two clients with
unify - for config see http://glusterfs.pastebin.com/m7a74bd29 (client) and
http://glusterfs.pastebin.com/m206785bc (server).
I'm using TLA 643 of the packages from http://projects.nlogy.cz/debian
(camel1cz builds them nightly), but saw the following problem already last
week with earlier patch versions.
When I write files with client-1, I can stat and read these files from
client-1 without problems. But I get wrong results doing an "ls -l" (zero
bytes) on client-2 and cannot read the file on client-2.
See the following example:
===> on client-1:
root at client-1 ~ # dd if=/dev/zero of=/glusterfs/testfile bs=1M count=100
104857600 bytes (105 MB) copied, 1.9773 seconds, 53.0 MB/s
root at client-1 ~ # ls -lah /glusterfs/testfile
-rw-r--r-- 1 root root 100M 2008-01-28 12:48 /glusterfs/testfile
root at client-1 ~ # dd if=/glusterfs/testfile of=/dev/null
104857600 bytes (105 MB) copied, 2.55219 seconds, 41.1 MB/s
===> on client-2:
root at client-2 ~ # ls -lah /glusterfs/testfile
-rw-r--r-- 1 root root 0 2008-01-28 12:47 /glusterfs/testfile
(=> zero byte size)
root at client-2 ~ # dd if=/glusterfs/testfile of=/dev/null
dd: opening `/glusterfs/testfile': Input/output error
