Disk hangs with 100% CPU

[bbunge]

I like this solution because you end up with NTFS formatted drives that can be read directly by a Windows PC. Does anyone know if Synology supports NTFS as a backup drive? I have read conflicting things on the Internet.

Synology supports external NTFS formatted drives. If you want to use your USB drives get a Raspberry Pi 4 and make that into a NAS. The Pi 4 has two USB2 and 2 USB3 slots. However, the cost of Pi has not come down. For about $120 you can get a DS120j single drive NAS, use one of your 8 TB drives in it and the other to back up the DS120J via USB3.

If up to Gigabit transfers are enough I would suggest HP Elitedesk mini, DELL Micro or Lenovo Tiny from eBay. They come cheaper then RPi kit and with Intel i3/i5-class CPUs - much faster than any RPi and with wider OS support. Some have SSD drives ready to go. Power efficient too, about 10W in idle.

Right from Synology (DSM 7.1):
https://kb.synology.com/en-global/D...er/system_externaldevice_devicelist?version=7

Synology NAS recognizes the following formats: Btrfs, ext3, ext4, FAT32, exFAT, HFS Plus, and NTFS. Any unrecognized external drive will have to be formatted first before being used on the system.

I run a 8TB WD Easystore (has WD Red drive inside) formatted for NTFS hanging off a Synology NAS as a backup target. Use the Synology Hyper Backup feature to backup the Synology to that external USB hard drive every night.

I know that QNAP does NTFS externally as well (eg, via USB). The internal can be forced to NTFS via some tricks, from what I read, but it's not recommended. The RAID support on these boxes prefers Linux formats, as that's what they are running internally... I see no reason to use NTFS on the internal drives, especially if you're on RAID anyway (ie, you don't have to access the drive via PC - just put another in, let the RAID sync, and carry on. No PC connection required.)

I found large files were being corrupted. Unless you follow up with a bit compare every time , which is impractical, those corrupted files will just trundle on down your back up regime. This should be able to work, but for now until and if it's fixed, I decided go in another direction.

Some say that this is because they are trying to add too many features to the routers. I am R&Ding NASes and the major players seem to be up to the same thing. For example I don't need to install a WEB browser on my NAS...

And I don't need to have my files exposed to hacking.... https://techcrunch.com/2023/04/13/hackers-claim-vast-access-to-western-digital-systems/?guccounter=1&guce_referrer=aHR0cHM6Ly93d3cuZ29vZ2xlLmNvbS8&guce_referrer_sig=AQAAABrD2IfgHauvPanlkmd_VxIEKfjYM5Rf_Bcp9V4wnBrSgnZWvWhKVH6KEg13BWJ_8m19AHnJD0BCSo3NFa9DZq_EXhiNCLiQEgt62qVvtGqNFoQ2ocA8T3XQlR2M6Owd8hCFq-8aIEOZqZ7rQQ_Q03eccvAu6aeAJ8sVnKNvL6im#:~:text=The hackers who breached data,not publishing the stolen data.

I know this is an old thread but I keep hoping the latest firmware would fix it. The problem persists through many updates till now 3.0.0.4.388_24221-gbedae75 again did not fix it. Santa is bring me a real NAS, I give upon SAMB USB support actual working reliability. Ever the optimist but maybe when I upgrade to a model with 2 Gig of memory?

250201 Samba update

Still on Firmware Version:3.0.0.4.388_24221. It turns out I have tried 4 different USB storage devices, 64 GB to 2 TB, most NTFS and one FAT32, USB Drives, HHDs and even a SSD in an USB enclosure. When I do a bit level file comparison about 50% of the time it returns one of a few bit errors, mostly on large files. But often when I repeat the same test it reports no errors. Right now the RT-AX88U is showing 97% RAM usage. I rate the speed as FAST but not when you factor in the possible errors.

So yes the new ASUSTOR AS5404T NAS is up and running with a RAID 5 HDD array and a RAID 5 SSD array and I’m not seeing this problem. With 3 of the prior devices mounted on the NAS also no problem. The other two would not mount. I suspect they were Formatted in the RT-AX88U. One of these I reformatted with WIN 10 and that drive now mounts and works in the NAS. The other I left alone and installed in the RT-AX88U for future testing.

IMO as for serious use I would avoid the Samba functions in the RT-AX88U running factory firmware.

I have to admit I never tried the Merlin software would that fix it?
