'Management service is offline' after 6.7.4 upgrade

In some past posts, this was linked to quotas being enabled on a volume with a lot of snapshots.

Try rebooting the NAS - if that doesn't help, try to do an OS reinstall from the front panel.  With current firmware the OS reinstall should clear the volume quota setting.  It also resets the admin password to password and the network configuration to use DHCP.  Data and other settings shouldn't be affected.

The boot menu options for the 4220 rackmount ReadyNAS are on page 33-34 here: http://www.downloads.netgear.com/files/GDC/RN2120/ReadyNAS_OS_6_Rackmount_HW_UM_10Dec2014.pdf

I did the same steps and did not return defualt

If you want to do a factory default, another way is to zero or unpartition the disks.  For instance, connect the drives to a windows system, run the windows disk manager, and then delete all the partitions ("volumes" in windows parlance) on the drives.

I want to do a factory default readynas  rn 4220.

I want any way to access the readynas 

Thanks

There are two ways I described earlier in this thread

• boot menu
• power down, unformat all the disks, then power up

Did you try either of those?

The first method (boot menu) did not work
The second methode (unformat all the disks) I did not understand it needs more detail

Thanks

• Connect each disk to a windows PC (USB or SATA).
• Open the windows disk manager (entering diskmgmt.msc on the run line will work). 
• At the bottom of the disk manager window you will see each disk in the system.  There's a graphic next to each disk that shows every partition (which Windows calls "volumes" for some reason).
• Right click on each partition in the graphic, and select "delete volume"
• Put all the disks back into the unpowered NAS and turn it on.  It will do a factory install (since all the disks are blank).
