RNDU4000 after update from FW4 to FW6 extremely slow - any suggestions/solutions?
Hi All, I´m new here and would really appreciate your help and maybe some hints. Got me a used Netgear RNDU4000 (ReadyNAS Ultra 4) from a friend with FW4.2.31 installed. After reading a bit I th...
The Ultra and Pro 4 aren't especially particular with the memory they use. I think I used A-Tech the last time I upgraded one. 2GB is the max you can use, with the specs StephenB gave. I find an updated Ultra4 to be about as fast as a 100 series. Not a speed demon, but very usable. I wouldn't recommend running much in the way of apps on one, though.
Thank you both for fast reply. Good to know to be not alone with this stuff ... :-)
Fast organized a 2 GB 200-Pin DDR2 SODIMM DDR2 667 2Rx8 module from a friend for testing.
I interrupted resync process, installed the 2GB (only one module possible) instead of 1 GB and started over.
Resync process states 60% @ 4x 1.5 TB physical HDD after approx. 6 hours since restart.
Cannot confirm that resync speeded up really but seems to be that the admin interface keeps alive now. Before doubling the RAM it happend to be that the admin page was not reacheable any more and "raidar" was unable to find the NAS after a while.
This really caused some frustration to me - but now waiting patiently to finish re-sync. Should be done tomorrow morning. Will see if system is still online ... and have a look at the mentioned report of the disk status. I´ve low level formatted all of them an run chkdsk before installing them to the RNDU4000 so I don´t believe that the disks are faulty somehow.
Will report ...
The Ultra 4 does have the slowest CPU of any ReadyNAS with an Intel CPU that can run OS6. It's the only NAS that can run OS6 that has a single-core Intel CPU
Unfortunatelly still the same:
After finishing re-sync in the morning NAS is offline and not reacheable. The loading process takes minutes and then no access possible.
So, in the end the doubling of RAM from 1GB -> 2GB was not really helpful and upgrade to FW6 is a fiasko.
Unable to work with this unreliable device and lots of spare time wasted :-(
