i have rnv-s2-0000 nv+ v1 (sparc) x-raid currently it gets stuck in the "booting..." sequence (with 4 drivers) i am trying drives one by one in slot 1, and so far only 1 hdd (previously in slot 3) is fine and booting (in slot 1, as a single drive). i get to the web ui the other hdd shows "err bad firmware" when booting by itself in slot 1 (previously in slot 4) i am trying to flash the redynas firmware on that drive, but i am struggling to find the proper boot image (i either get "os index error" or "bios info, usb init" messages on readiness) could someone point me at the correct image for the usb flashing of the possibly corrupt firmware image on the drive for 4.1.8 nv+ v1, please? then i can write it onto a bootable fat32 usb stick and go from there (tftp would also be fine, if someone has the image) and of course, i have other 2 disks to deal with (i suspect - corrupt), but i figured i can at least get this one going first thank you!66Views0likes7CommentsOS Reinstall worked ... UPS issue?
First off many thanks to Netgear and everyone in this forum...after reading several posts from here...I was able to fix my issue after some initial panic. But I'm wondering what happened or if I have the UPS setup wrong. My RN104 (with 4x8TB drives and latest FW) has been trucking along for almost 10 years with no issues..but last night, our power went out for 5-10 minutes and the unit turned itself off, despite being physically connected to a UPS. I also have a synology NAS connected to same UPS and it has the USB cable connected to it. My Netgear RN104 is monitoring the UPS using the network SNMP connection from the synology. When i powered on the Rn104, it booted up fine to 100% but then totally shut off within 30 seconds. Same thing after several attempts and connecting power directly to wall. I pulled out the drives and when I booted up, it was fine and I could connect to it browser. Put the drives back in, praying for a miracle, but NADA...same behavior, shutdown immediatley following boot up. I started to panic given that Netgear no longer supports Readynas...but I kept reading and researching. Eventually, from the posts here and the Netgear manual, I decided to try the OS reinstall option and that did the trick...I was able to login and deal with minor IP address issues..but no data loss! The logs show when the power went out and came back...but then this entry seems odd: Jun 21, 2025 01:15:42 AM System: The system is shutting down. Jun 21, 2025 01:15:25 AM System: UPS UPS () is forcing shutdown. After I restored, I deleted the UPS SNMP entry(just in case)...but could this be a bug in OS 6 code to read the network UPS? or did I set up wrong? Anyone use a Readynas with SNMP UPS and the codes it receives? No issues on the Synology NAS with the same UPS(via cable) when power came back online. Also wondering if I should start thinking about a replacement/newer unit. But this is my 2nd Netgear ReadyNas I have owned and I think they work perfect for my use cases. Again, many thanks to this community. Sorry for long post...TLDR: Is there something wrong with UPS codes being read by Readynas OS6 or time to replace?80Views0likes5CommentsNetgear RNDP6000 in safe mode
My NAS went into safe mode this afternoon. My conclusion is that i might need to re-install the OS. The documentation page on the netgear site is unavailable and i have found some instructions but are not explicit enough to move forward. Could someone please provide detailed instructions as i cannot afford to lose the data on these disks. This NAS had been working fine and for no reason lost contact with the network. I needed to power cycle it and it has set itself to the basic configuration. I can see that the disks are all present and in a RAID 5 configuration.Solved107Views0likes4CommentsReadyNAS104 assistance needed
Hi, I have an old ReadyNAS 104 that apparently just crashed. I can get it to reboot and I can access it from a browser but it shows the volume as new? I have 4 - Toshipba 3 TB drives in a RAID 4 configuration. I have attempted to access the BOOT menu by rebooting the NAS with my finger on the power button but that does not appear to work. When I look at the drives they are all showing green but "new" and the volume I had for many years is now gone. Please help82Views0likes2CommentsReadyNAS Pro 6 - Stuck on booting while checking fs
I have searched for similar errrors on here, but none seem to either work or be related as to my situation. My Pro 6 just started to freeze a couple days ago while it was running. I had updated it to OS6 a long while ago. Thinking it might just be a random error, I restarted the device and now it gets to the checking root fs and stops around half way (sometimes more or less). I have tried the following: OS Reinstall - Completes and boots to same percentage. Disk Tests ran fine and rebooted itself (though now this is no longer an option in the boot menu) USB Recovery ran and shutdown. Boots back to same percentage. Tech Support mode works Tried start_raids and it seemed to see every drive. Ran some mdadm commands to examine the drives and array as found in other posts on here with no glaring errors found. Running a 'smartctl -t long /dev/sda' now. Not sure what else to do to get it to boot so I can get my files (prefer it to continue being useful but can get soem other NAS and move my data as long as I can get to it). Thoughts/ideas/help? Thank you.220Views1like27CommentsreadyNAS 104 doesn't start properly
Hello community, I'm french so i'm sorry for my english level. Topic: Suddenly my NAS didn't start properly. I pushed on start button and the NAS started but stopped after 2 seconds. I retried but did the same. I have tried to change the electrical plug but didn't change the situation. I have get out the 4 hard drives and the NAS started, booted during 1 min until 100% and writen on the front screen "in safe mode". I tried again installing the 4 hard drives and the problem appeared again. Now i don't access to my datas and i dont know if the hard drives are corrupted or if the problem comes from the NAS itself?! I had the opportunity to get a second identical NAS 104 but i'm afraid to install my hard drives into, starts the Readynas and loose my datas. If i remember well i'm in raid X. My last opportunity is to use RS raid retrieve software but it should be an other story! If anybody has a suggestion please let me know!488Views0likes33CommentsSparc NV+ says "Disk 4 sync"
Unit's been working great but Tuesday morning I tried to "Download all logs" and waited for the "Download to..." dialog to instead browser saying it had lost contact. Power button seemed non-responsive so I pulled the plug on it. Boot try appeared to be working in that it showed "Quota chk" and blinking Act led for a few hours but then the Act led extinguished. Late that same day still sitting there apparently dead I ran RAIDar and it said "File system 100%" but still not booted or running services or responding to kiTTY though I could ping it. Made another identical attempt yesterday morning, to identical results this a.m., so I tried next Boot Menu's Skip volume check. After a couple of hours display says "Booting..." and "Disk 4 sync" and while the blue Power button is pulsing, the Act LED has not blinked for quite a while and the 4 disk LEDs are steady. Question is: do I wait on this thing as if it is indeed doing something, or should a "Disk sync" be accompanied by an Act or Disk LED blinking? Oh, now RAIDar is not finding it either which is not a happy thing. Running last 4.1.16 iirc.98Views0likes7CommentsRN314 don't boot anymore after trying to fix "no space left on device" error.
Hi, Here's the full story that led me to a ReadyNAS RN314 that no longer starts with a "flush_space+5a" message on the LCD. Actually, after seeing that I lost (I mean visible on the network) the SMB, NFS shares from my RN314 I tried to login via the Web UI. But each time it was looping on the login screen until it asked me to follow th recovery password procedure that I did not follow. Instead I logged in via SSH and I discovered that the OS was complaining about "no space left on device" on the / (root) making /tmp unsuable for all the pplications! I ran the command df to see where the space was really missing and there was still almost 1TB on the data file system (/dev/md127) and 1,3 GB on the / (/dev/md0) and ieven the I-nodes were not used at 100%. Weird as I was not able to still create a file in /tmp (no space left on device), it should be something related to btrfs. I deleted some log files from /var/log to free some MB and I tried to check the /dev/md0 with the command btrfs filsystem check / (if I rember well the syntax). It ran the night and when I wake up the ssh connection was closed. I reconnected and it says that the filesystem was in read only. Then I asked a reboot and unfortunatly the NAS stop booting with the LCD displaying "flush_space+5a" msg and since it does boot anymore. After googled a bit, I found that maybe reinstalling the OS via the boot menu can soved the issue without loosing all my 8TB of data. I tried and unfortunatly no change I got still the "flush_space+5a" like in the normal boot mode. I don't want to try the USB recovery method as I understood well the /dev/md0 will be reflashed and all my data on /dev/md127 will be reset loosing all my data. I there a way to boot like in Tech support mode (via the boot menu) or an other way to gain access to my data that I could backup on an external disk before resting everything. I hope I will not loose almost 10 years of data. Br, Cataldo. PS: The firmware installed was the latest available.Solved2.4KViews0likes26Comments
