RaidR
Any plans to get a driver for Mac OS 10.15 Catalina for RaidR?
Hi PWS442,
RAIDar 6.5.0 for Mac OS Catalina was already fixed so you should be able to install it now on that version. We just tested it before we were able to use RAIDar on Catalina.
Regards,
Still waiting for a Catalina version for the MacOS. RAIDar_6.5.0.dmg will not even install as it is a 32 bit executable.
“RAIDar.app” needs to be updated.
The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.
I cannot access the RN314 via the Admin screen. Was hoping to get to the logs and see what is wrong with my NAS.

Thank you, oddly yesterday, the .dmg file did not install a new executable, but today it successfully installed 6.5.0. Now only if the resync would finish so I can replace disk4. I have gone from redundant to degraded.
As I said, yes I am resyncing, and yes, I am making a backup. Concurrently they are both active. That was the jist of my concern.
I am 40.8% complete with the resync. 2 days ago was at 30%. My backup probably has just as long to complete.

If disk 4 is the disk that is resyncing, then you could simply pull it. That would probably speed the backup, and it would also eliminate any chance that the resync will uncover a problem with one of the other disks.
However, if it's not about disk 4, then you probably should leave it alone and hope that the backup completes successfully.
It is disk 4. If I replace it, won't that start the resync over again? And, is that a bad thing if it is already degraded? Very confused.
Couldn't wait anymore. Pulled it. "Recover: 0.01%".
Pray for me!

Normally with XRAID/RAID-5 you have protection from a single disk failure. When the system is resyncing, that protection is lost - so the volume is described as "degraded".
Disk 4 was already not in the array (the resync was trying to add it back). The risk you were running is that another disk might have some errors. If that were to happen, the volume itself would fail, and you'd lose all the data.
Pulling disk 4 actually reduces the odds of that happening. The resync needs to read or write every sector on all four disks. The backup doesn't require that - for instance, it doesn't need to read free space at all. In any event, you were going to replace disk 4 anyway. So there's no point in trying to add a failing disk back into the array - it just was increasing the odds of losing your data, and slowing down the backup speed.
The best strategy is to have a backup plan in place, so you are always prepared for a volume failure. RAID protection is nice to have, but it isn't enough to keep your data safe.
BTW: Kudos for the new UI in RAIDar. Much cleaner than the older versions.
