Raid5 is broken and separate raid0 and raid1?
I made the raid5 with 6 disks and used for a year. Now I my RN316 is broken then I try to connect these disks to another linux. However I checked every disks, somehow there is raid0x5disks and raid1 x 1disk It looks like raid5 fall aparts into raid0 and raid1. Is it possible to use these as raid5 forcebly?? such as 5 drives, /dev/sdd3: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : 5cda431d:eb21dd6d:849d9d92:636a0c72 Name : 0a438048:FILES-1 Creation Time : Wed Jun 11 08:24:46 2025 Raid Level : raid0 Raid Devices : 5 Avail Dev Size : 15618351694 (7447.41 GiB 7996.60 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 6ac2adc5:992e062a:7e8aa6d7:5885b27a Update Time : Wed Jun 11 08:24:46 2025 Bad Block Log : 512 entries available at offset 8 sectors Checksum : d77027db - correct Events : 0 Chunk Size : 64K Device Role : Active device 1 Array State : AAAAA ('A' == active, '.' == missing, 'R' == replacing) one drive is like this, sudo mdadm --examine /dev/sdf3 /dev/sdf3: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : 38792c55:ec30a05d:ef132979:1abc74c9 Name : 0a438048:FILES-0 Creation Time : Wed Jun 11 07:15:43 2025 Raid Level : raid1 Raid Devices : 1 Avail Dev Size : 15618351680 (7447.41 GiB 7996.60 GB) Array Size : 7809175808 (7447.41 GiB 7996.60 GB) Used Dev Size : 15618351616 (7447.41 GiB 7996.60 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=263912 sectors, after=64 sectors State : clean Device UUID : df652525:c37b0a23:214456ea:deba215a Update Time : Thu Jun 12 02:46:05 2025 Bad Block Log : 512 entries available at offset 264 sectors Checksum : 295491c1 - correct Events : 2 Device Role : Active device 0 Array State : A ('A' == active, '.' == missing, 'R' == replacing) Swap area(/dev/sd*2) somehow keep raid10 sudo mdadm --examine /dev/sdf2 /dev/sdf2: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : 860482db:bc8f628a:3b14dc96:8fc010a0 Name : 0a438048:1 Creation Time : Wed Jun 11 07:15:43 2025 Raid Level : raid10 Raid Devices : 6 Avail Dev Size : 1044480 (510.00 MiB 534.77 MB) Array Size : 1566720 (1530.00 MiB 1604.32 MB) Data Offset : 4096 sectors Super Offset : 8 sectors Unused Space : before=4016 sectors, after=0 sectors State : clean Device UUID : 7300c357:529e4410:a14c33fc:e11bb3c2 Update Time : Wed Jun 11 17:09:12 2025 Bad Block Log : 512 entries available at offset 16 sectors Checksum : a8d95fb5 - correct Events : 19 Layout : near=2 Chunk Size : 512K Device Role : Active device 0 Array State : AAAAAA ('A' == active, '.' == missing, 'R' == replacing)What is the filesystem RN316 using as raid.
I have 6 raid disk used in RN316 Now I connected to these disks to another machine and assmble the raid. $sudo mdadm --assemble /dev/md130 /dev/sdf3 /dev/sde3 /dev/sdd3 /dev/sdc3 /dev/sdb3 mdadm: /dev/md130 has been started with 5 drives. However, I can not mount this, $sudo mount /dev/md130 /mnt/raid mount: you must specify the filesystem type it requre the filesystem type. So I try this but in vain.... $sudomount -t ext4 /dev/md130 /mnt/raid mount: wrong fs type, bad option, bad superblock on /dev/md130, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so Raid looks working $sudo mdadm -D /dev/md130 /dev/md130: Version : 1.2 Creation Time : Wed Jun 11 08:24:46 2025 Raid Level : raid0 Array Size : 39045879040 (37237.05 GiB 39982.98 GB) Raid Devices : 5 Total Devices : 5 Persistence : Superblock is persistent Update Time : Wed Jun 11 08:24:46 2025 State : clean Active Devices : 5 Working Devices : 5 Failed Devices : 0 Spare Devices : 0 Chunk Size : 64K Name : 0a438048:FILES-1 UUID : 5cda431d:eb21dd6d:849d9d92:636a0c72 Events : 0 Number Major Minor RaidDevice State 0 8 83 0 active sync /dev/sdf3 1 8 67 1 active sync /dev/sde3 2 8 51 2 active sync /dev/sdd3 3 8 35 3 active sync /dev/sdc3 4 8 19 4 active sync /dev/sdb3 $less /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] md130 : active raid0 sdf3[0] sdb3[4] sdc3[3] sdd3[2] sde3[1] 39045879040 blocks super 1.2 64k chunksDisk reuse after factory default
I am using ReadyNAS RN316. There was some problem occurs ,so I remove the 6 disk(raid5 array created) then factory default. Factory default success and restart. However if I push the 6 disks back to the trays, RN316 starts formating automatically or ditects the array same as before????readyNAS 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!RN102 change disk, read-only data volume after delete a SMB Share
With a RN102 with only one 2 Tb disk I have some SMB Shares and one Iscsi target. Yesterday I delete an SMB Share and since then I receive a message saying “There is an error on data volume and it’s turned on read only. We recommend doing a backup” (or something like this, I translate the Spanish message). The current running firmware is 6.10.10. I have some questions: The critical point is that the Iscsi target is used to backup purposes. Can’t I connect and extract data in read-only mode? My first try gives an error, but I don’t it’s because I try to write a file first I have I new WD Red compatible disk and I like to extract the current disk and save It (for try to recover and access old backups). Then install the new one and start a new backup set there. When I will start the NAS with de new disk It start from the scratch? with original factory firmware? I have to configure RNAS Name, IP, shares and iSCSI targets? If I stop de RNAS and start with one or other disks (the old one, and the new one) it’s like if I use two independent RNAS ? I think this is the best config for me: config the new backup set on new disk and save the old one as an independent NAS. What about save current NAS configuration file and restore it on the RNAS with the new disk? It maintains SMB Shares, iscsi targets, notification config etc.. (without data … but metadata) Thank in advancenetgear readynas 316no volume exists. Netgear recommends that you create volume before configuring
Hello , I am getting the error netgear readynas 316 no volume exists. Netgear recommends that you create volume before configuring other settings. I have a readyNAS 316 with 6 disks each 3TB and on RAID 5. Disk 4 degraded and i have to look for a new disk in a period of 2 weeks. On replacement, I switched off the NAS, removed the degraded disk and inserted the new 3TB disk. After booting, the NAS was giving the above error. Suddently Disk 1 was showing missing. I rebooted the NAS but was still showing the above error. How do you go about it in order not to lose data? Does it mean the new disk is faulty? The device is still recognising 13.2 storage. 6 disks by 3tb should be 18TB. Can someone help me kindlyremove inactive volumes to use the disk # 2,3,5,6
StephenB My RN316 is configured on Raid 5 with 6 disks. Disk 4 degraded. It took long to replace the degraded disk. On replacing disk 4, disk 1 became inactive and missing. The NAS did not resync, but instead its gving me the error "remove inactive volumes to use the disk # 2,3,5,6" and when i go to shares, it says No vulumes exists. NETGEAR recommends that you create a volume before configuring other settings. How can i make it to rebuilt tha data or i need 2 disks. The new Disk 4 in the start was showing a separate volume but i formated it. All the disks are red and showing that they are healthy.ReadyNAS 214 won't recognize replaced drive
RN214 I've had for a number of years had its first disk issues: lots of ATA errors for disk 4 and "degraded" status for the RAID-5 volume. I bought two new drives from Newegg (Toshiba DT01ACA200, same model as the original one) and performed a hot swap, but the RN214 never acknowledges that the new drive is there or starts to resync the data... in the on-screen diagram, it shows only three drives This is the same whether I use either of the new drives. If I put the original drive back in place, it shows up, and the RN214 logs start showing the ATA errors again. This leads me to suspect that there's nothing wrong with the drive slot. The alarms dialog shows the old drive being removed and reinserted, but nothing about either of the new drives. Any suggestions will be greatly appreciated! RN214 details: Firmware: 6.10.8
