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.
