Ways to Recover Data from Crashed Synology Volume.How Do I Know If the Problem Is with My Synology NAS Or Disk(s)?.Some common reasons that may cause Synology volume crash.If any of the volumes in Synology NAS crashed, it means that there are problems with the NAS or installed disks. The Synology NAS has Storage Pools, each containing one or more volumes. Synology Network Attached Storage (NAS) is an advanced storage device that you can use to connect office or home network and to store files and other data. We’ll also discuss the solution to recover Synology volume data if multiple disks are physically or logically failed.

In this guide, we’ll discuss how to restore data from crashed volume if the disks are healthy. But with prompt action, you can get back your mission-critical business data. LV UUID Pl33so-ldeW-HS2w-QGeE-3Zwh-QLuG-pqC1TESummary: Synology volume crash is a critical situation that can lead to permanent data loss. VG UUID pHhunz-cg0H-Fkcg-na1y-AAcT-D9fU-gdDTet PV UUID nolEeP-0392-QvMt-ZOkW-1JDr-COn4-QybVK7 PV UUID 2NkG9U-9Rh6-5xFW-M1iM-GA0f-nbOd-aJHEUS PV UUID p7cJsO-la6l-vXp7-ga51-4ugu-he7H-SeoHgZ LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
Then try the following (obviously stop if you see something you don't like):Ĭouldn't find device with uuid bocvSr-hmj0-LUH0-BM8g-BXBS-TicT-LbjYQ9. So if you don't have ssh access to your system already, please turn it on. But since you have a consistent and operating array set (albeit degraded) we should try and start the Storage Pool and give you an opportunity to offload your data before doing anything else. If we have an ARRAY that is crashed because there are not enough members to start it, we can evaluate the serials and determine how much risk we will incur by forcing it back into service. All writes are serialized so that the system knows this for sure.

I am not 100% certain why your Storage Pool 2 is indicating crashed as all the members are clean and degraded.Īfter /dev/sda went offline for whatever reason, if the arrays are written to, they are no longer consistent with the missing disk so it won't be reinserted automatically. On the Storage Manager Overview screen, there should be a button to repair the System Partition and those members will be restored. The "System Partition" error is because there are two members that are not participating in md0 that should be. Md0 is the DSM operating system spanned (via RAID1) across all disks, and md1 is the Linux swap partition similarly configured. 0.9TiB of space is wasted on /dev/sdb as the largest drive, since there is nowhere available to replicate the data.
This grid might help you see things more clearly: I am bit lost now, does each one have a separate volume and the total combined is the mdadm -detail /dev/md4

I was going to try what Synology suggest and load Ubuntu on my PC and try and restore the volume using the mdadm -Asf & vgchange -ay I have a Synology DS415+ and the storage pool crashed without warning.Īll drives were showing Healthy and I need help identifying what the problem is and how to recover the data (if possible).
