Stuff…

A fresh Acronis EchoServer install on CentOS 5.4 was taking a long time to execute the “trueimagecmd –list” command and was throwing lots of meesages in the dmesg/log files such as:

session_init: OK. kdev=9:0, bs=1024.
session_init: OK. kdev=9:1, bs=4096.
end_request: I/O error, dev fd0, sector 0
end_request: I/O error, dev fd0, sector 0
end_request: I/O error, dev fd0, sector 0
end_request: I/O error, dev fd0, sector 0
end_request: I/O error, dev fd0, sector 0
end_request: I/O error, dev fd0, sector 0
session_init: OK. kdev=9:0, bs=1024.
session_init: OK. kdev=9:1, bs=4096.

It turns out it was the floppy kernel module loaded that was causing the slow down. Checked to make sure the floppy module was loaded: lsmod | grep -i floppy

Are sure enough it was.

After removing it with: rmmod floppy

The trueimagecmd command ran fine.  To stop the floppy module starting in future we edited the “/etc/modprobe.d/blacklist” file adding  “blacklist floppy”.

Other symptoms may be the following error when you try to mount a index of a backup:

No signal from child in 60 sec.
