Future HDD sizes
Hi I currently own a Readynas pro with 1.5tb drives with x-raid but there are going to be 4tb drives out at the end of the year. I heard there is a volume size limit on the Readynas something like 16t...
Yes with dual-redundancy in a 6-bay ReadyNAS filled with 4TB drives, you would still be under 16TB.
If less than 6 drives are installed and the array is currently redundant then a switch to dual-redundancy would definitely be a good idea. See Converting and XRAID2 system to dual redundancy
If 6 drives are currently installed then switching to dual-redundancy would still be a good idea, however it would require a factory reset. With 4TB drives rebuild times would be even longer than now and as disk capacities get larger the risk of dual-disk failures becomes a bigger concern. It's not as uncommon as some might think. If all drive bays are full then the only way to switch to dual-redundancy would be to:
You may also wish to consider running X-RAID2 dual-redundancy. This does provide extra peace of mind than the default single-redundancy. To switch to dual-redundancy you could:
i. Backup all data
ii. Verify backup is good
iii. Upgrade to latest RAIDiator (currently 4.2.17: http://www.readynas.com/RAIDiator_x86_4_2_17_Notes
iv. Do a System > Config Backup
v. Do a factory reset with four or more disks in place either via System > Update > Factory default or via the boot menu (http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu
vi. Discover the NAS using the latest RAIDar (http://www.readynas.com/downloads)
vii. Click setup during the 10 minute countdown
viii. Choose X-RAID2, tick dual-redundancy and confirm your choice
ix. Restore Config Backup
x. Restore data from backup
xi. Re-install and configure your addons.
Btw if you download your logs (Status > Logs > Download all logs), extract the zip contents and look at initrd.log, what is the oldest version of RAIDiator listed?
