[Gluster-devel] booster translator error

[nicolas prochazka]

Hi,
I do some test with booster translator, and i ve found some issue :
my test is very simple, client1  -> server1

if i do :

revelation vdisk # dd if=base of=dest bs=10MB
629+1 records in
629+1 records out
6290378752 bytes (6.3 GB) copied, 135.844 s, 46.3 MB/s

all are ok.  I'm not using booster in this case.

if i do :

LD_PRELOAD=/usr/local/lib64/glusterfs/glusterfs-booster.so dd if=base
of=test bs=10MB
dd: writing `test': Transport endpoint is not connected
1+0 records in
0+0 records out
0 bytes (0 B) copied, 0.113639 s, 0.0 kB/s
then i do a ls :
revelation vdisk # ls
ls: cannot open directory .: Transport endpoint is not connected
if i do a cd /  and then cd /mnt/vdisk   , it works again.


I'm using big file, sometime, /mnt/vdisk seems to be inacessible, dd
shows this issues all the times.
