Should I update eyeOS Joomla plugin?

 

Creating, assembling and rebuilding small array is fine. But, things started to get nasty when you try to rebuild or resync large size array. You may get frustrated when you see it is going to take 22 hours to rebuild the array. You can always increase RAID resync performance using the following technique

/proc/sys/dev/raid/{speed_limit_max,speed_limit_min}
The /proc/sys/dev/raid/speed_limit_min is config file that reflects the current "goal" rebuild speed for times when non-rebuild activity is current on an array. The speed is in Kibibytes per second, and is a per-device rate, not a per-array rate . The default is 1000.

 

The /proc/sys/dev/raid/speed_limit_max is config file that reflects the current "goal" rebuild speed for times when no non-rebuild activity is current on an array. The default is 100,000.

 

To see current limits, enter:

# sysctl dev.raid.speed_limit_min
# sysctl dev.raid.speed_limit_max

To increase speed, enter:

echo value > /proc/sys/dev/raid/speed_limit_min

or

sysctl -w dev.raid.speed_limit_min=value

In this example, set it to 50000 K/Sec, enter:

# echo 50000 > /proc/sys/dev/raid/speed_limit_min

or

# sysctl -w dev.raid.speed_limit_min=50000

 


 

If you want to override the defaults you could add these two lines to /etc/sysctl.conf:

dev.raid.speed_limit_min = 50000
dev.raid.speed_limit_max = 200000
