Hi everyone, I just got here and my mybook live duo installed openwrt, but the writing speed is very slow：
root@MyBookLiveDuo:/mnt/Data/dlna# time dd if=/dev/zero of=./tmpfile bs=1M count=1024
1024+0 records in
1024+0 records out
real 1m 45.14s
user 0m 0.02s
sys 0m 11.03s
9.7M/s
Then remove the configuration 'async,noatime,nodiratime' from the configuration file /etc/config/fstab
root@MyBookLiveDuo:/mnt/Data/dlna# time dd if=/dev/zero of=./tmpfile bs=1M count=1024
1024+0 records in
1024+0 records out
real 2m 11.90s
user 0m 0.01s
sys 0m 12.21s
After deploying the 22.3.5 version many times, I tried to use rsync to copy movies from windows to /mnt/Data, but all failed, the system did not respond, and the address of mbl could be pinged, Luci could not be opened, and the root password prompt could not Log in. After doing dd many times, I found that 22.3.5 can no longer be used, so I chose 18.06.2 version. This version will at least not dd the image. But writing to the file under 18.06.2 also puts the system into read-only mode or becomes unresponsive. The rsync speed is less than 4M/s, and mbl not responding when the transmission speed reaches 5M/s.
My judgment is the problem caused by the writing speed of the hard disk. Just to mention a word, the hard disk and mbl have been stored for many years, and they were only recently taken out to play.
