ReadyNAS 104 RAID5: 'Remove inactive volumes' after crash during resync - recovery needed
Hi all, I have a ReadyNAS RN104, firmware 6.10.8, with 4x WD Red 3TB (WD30EFRX) in RAID5 (X-RAID). I'm hoping for guidance on safely reactivating my volume without losing data - I do NOT want to guess or experiment further, since I already know that's risky. SETUP / TIMELINE - Disk in bay 3 was reported FAILED (confirmed via admin panel, matching blinking LED, and SMART data showing high ATA error count / pending sectors, while bays 1, 2, 4 were clean or only minor). - I bought an identical replacement WD30EFRX and did a partial backup (docs, photos, music) to an external USB drive before touching anything. - After disconnecting the external drive, the system automatically started a resync on the degraded volume. - ~18 minutes later, per the system log: another disk (Channel 2, log-based indexing) went from ONLINE to FAILED during the resync, the resync target disk (Channel 3) went from RESYNC back to ONLINE, and the volume health changed from Degraded to Dead. The system then warned it would auto-shutdown in 30 minutes. - I shut the system down manually and physically replaced the old failed disk in bay 3 with the new one. - On power-up, I got: "Remove inactive volumes to use the disk. Disk #1,2,4." and the Volumes page shows two entries: "data-0" (8.17TB data, RAID5, red status) and a second "data" volume (0 data, "RAID unknown", red status). CURRENT STATE (from volume.log dump) - RAID data-0: Level 5, State: inactive, Members: 4, but only 3 disks currently listed under it: sdd (bay1), sdc (bay2), sda (bay4) - all three show no Reallocated Sectors, no Uncorrectable Sectors; sdc has Current Pending Sector Count: 2, others 0. - The "data" pool (the second, empty one) has a null UUID (000...000), Type: btrfs, 0 disks assigned - looks like a stale/ghost volume reference, not a real data container. - Maintenance history log shows two earlier resilver operations (2026-07-11 and 2026-07-25) that both completed but left the pool "degraded", and a third resilver started 2026-07-27 that has no end_time/result - this is the one that was interrupted by the crash described above. - New disk in bay 3: brand new, 0 power-on hours, not yet part of any pool (no Pool: line in its log entry) - as expected, it hasn't rejoined the array yet. WHAT I'M ASKING Based on what I've read about ReadyNAS event-count mismatches after an unclean shutdown/crash during resync, this looks like it could be a recoverable case (3 consistent disks, no reallocated/uncorrectable sectors) rather than a true double-disk failure - but I don't want to force-assemble anything myself without being sure of the exact commands/parameters for my array, since I've read that experimenting further can easily make things worse. Netgear won't open an official support case since the RN104 is out of support. I do NOT have a complete backup (only partial, done just before the crash), so I'd really appreciate guidance from someone experienced with forcing a safe mdadm/BTRFS re-assembly on ReadyNAS OS6, or confirmation on what "Remove inactive volumes" actually does in this specific situation before I click anything. I have the full log zip ready and I'm happy to share it privately (PM) with anyone willing to take a look - didn't want to post it publicly here. Thanks in advance for any help.
RN212 can't seen by time machine anymore
Dear forum experts, my RN 212 vers. 6.10.10 run flawless for a long time... Raidar vers. 6.5.0 can still see the NAS and tell me everything OK, aka two green light for the two 4TB disc bays. RN 212 system overview show, 3.02 TB free on disc and of coarse is set to use SMB. macOS Monterey 12.7.6, TimeMachine should backup an internal SSD with 2TB Now it reports "Communication error, check DNS and Proxy settings" The only thing i had changed recently, is a new mesh 7 Wifi, for the house. But the RN212 is connected to the Mac by wired LAN, thus a mesh Wifi shouldn't affect the LAN settings? Any ideas from forum users welcomed BTW: When logging in i was forced to set a new pw, afterwards i've been told all usernames including my old one (Bob) are used and i have to create a new one. But every name i keyed in, was already taken, thus i endet with this stupid one...sorryFor NETGEAR NAS Storage

SNMP shutdown of ReadyNAS 6.10.9 using CyberPower UPS not working
CyberPower rack-mount UPS CP1500PFCRM2U powering 4 ReadyNAS boxes (212, 314, 424, 528X). All are Ethernet connected including UPS using RMCARD205 optional Ethernet Card. ReadyNAS are all connected to the UPS via SNMP like the example shown below. When UPS is on battery, battery can drain all the way to 0% and NAS units never gracefully shut down. Why? Is a NUT server mandatory for this to work? My rack has a Home Assistant OS laptop, running Network UPS Tools integration. It can monitor the UPS over SNMP.
