Until now I used servers with a maximum of 2TB of hard disk and used RAID 1 for software without problems. It took about 1 day to synchronize. Now I am faced with the problem that with the 4TB disk it will take about 1 week and when it does, it will have to start again.
I have increased the writing speed to the maximum in the files:
/proc/sys/dev/raid/speed_limit_min
/proc/sys/dev/raid/speed_limit_max
And that has somewhat improved the timing, but not much. This is the result of:
[[email protected] ~]# cat /proc/mdstat
Personalities : [raid1]
md2 : active raid1 sda3[0] sdb3[1]
3872806720 blocks super 1.2 [2/2] [UU]
[=======>.............] check = 38.3% (1486756992/3872806720) finish=34929.4min speed=1138K/sec
bitmap: 20/29 pages [80KB], 65536KB chunk
md1 : active raid1 sda2[0] sdb2[1]
523712 blocks super 1.2 [2/2] [UU]
resync=DELAYED
md0 : active raid1 sda1[0] sdb1[1]
33521664 blocks super 1.2 [2/2] [UU]
resync=DELAYED
unused devices: <none>
That could be happening? I appreciate any suggestions or ideas on what else to look at, thanks.
