This is a known bug, where the sector writes shows incorrect. Netinstall with the v5.21 from the webpage will fix it.
Unfortunately it didn't help in my case.
I have 951-2n, operational from november 2012 (with 5.21). it is performing quite well, and currenlty it is working with 5.22 firmware.
I had processed with netinstall (5.22), but write-sect-total is still extra large.
It is not growing rapidly (normally i believe), so the most important thing was solved, but how to force my 951-2n to show the correct amount of total written sectors or clear it to the initial value ?
You can find my current resource status below, how to solve this issue ?
[admin@951-2n] /system> resource print
cpu: MIPS 24Kc V7.4
I can physically access this unit not very often, because it is installed on remote site, and for next three days i will be able to perform additional steps, so please advice what to do,
or inform that i have to deal with this enormous number of written sectors.
