  1. Hello. Does anyone can advise to me if I can copy (rsync) entire volume data (not the one where package are installed) from xpenology nas1 volume2 to nas2 volume2 ? I seen a lot of @eaDir and @DS_Store folder into my nas1 volume2 and I don't know the bad issue possibility if I copy too these ones to the other nas. Any advise here ?
  2. fter a new reboot, the DSM seen the third disk as free and initiated I was able to repair the raid. The disk SMART info show this into his history some search on the web suggest that it can come from a bad sata cable...does a sata cable can become bad after 4 years of good state ? during the repair of may array, as I don't have an answer from anybody, I'm working now to delete all @EADIR & @DS_STORE folders from my backup data, in case of need to rsync all again to my DSM.
  3. I followed good advises from @flyride found there : and did a # vgchange -ay # mount -o clear_cache /dev/vg1000/lv /volume2 All my data was again accessible with SSH this gived me the way to do a # rsync -avzh /volume2/ /volume1/MOUNTNFS/volume2 and transfer all to a mounted volume folder from another nas to the first one. This had took a while but at the end I got now a copy from all ma data. Then I had removed completely my volume 2 from my DSM et recreate it. again took a while for the first consistency check and after did a # rsync -avzh /volume1/MOUNTNFS/volume2 /volume2/ (took again days to complete the transfer) I was happy but too fast, as my DSM now hangs a lot and I got issues with some permission/owner folders. I realise now that it was apparently a big mistake to left rsync handle the @EADIR and @DS_STORE folders, as i didn't made exclusions for those ones. My DSM become often unresponsive with Filestation during some copy jobs or change owner settings of some folder, I did a # reboot from ssh and there big scare, as the first restart the DSM didn't came back. OK, is it the end? do I need to re-install all xpenology ? after 2 restart, still front of a DSM not showing, I decided to start without my second volume and pull off the 4 disk once shutdown. This made the trick and the DSM came back correctly with only the volum1. Shutdown again, put back my 4 disk volume2, and yes!! the DSM came back with my 2 volumes. The DSM did again on a consistency check on the volume 2 and then proposed me to fix the file system from the third disk . I did the click on the repair link proposed but again the system hang and no acces at all to DSM again. @flyridedoes it mean that my third disk is really dead ? does anybody can help me here, I'm lost. after a volume crashed, now I'm facing with a degraded one that refuse to be fixed.
  4. Well, here I suffer a lot after days of rsync to backup my data to another Nas and rsync again backin to the recreated volume 2 I discover now others issues (seem to be not a good procedure to rsync ALL with the @EADIR and @DS_STORE folders included) All my data are back into my volume 2 but the DSM hangs a lot when I use filestation and some folders got now root as owner. Once , the system completly hangs I asked a reboot with ssh and DSM didn't came back. I had completly shutdown, remove my 4 disk (volume from the nas, restart the nas with Only volume1 and the DSM came back. Shutdown again, put back my 4 disk and restart, the DSM came back with the 2 volumes and all my data. But it is now making a consistency check of my volume 2 and my disk 3 say error file system, with the storage manager that propose me to fix it. I'm waiting now the end of the consistency check before do anything else. But I'm afraid I will need to delete my volume again and again do an rsync WITHOUT @EADIR and @DS_STORE folder this time. what a painy a... situation and ways time here for me. for your case what's your result with the command # vgchange -ay I think you maybe not working on the correct device here as you got a VOLUME with SHR where md2 is the disk device you need to work on the logical volume created by the raid array here this is why I ask you to do a # vgdisplay -v to see it did you tried yet to mount the volume in read only mode without his system file cache ? # mount -o clear_cache /dev/vg1000/lv /volume1
  5. Like said Flyride, your data are still there, but here it's your DSM files systems that are now messy, then start from another DSM fresh will maybe give you more opportunity to get back your data. happy Easter to you
  6. Yes you probabely right I was thinking about a repair of your array with the spare 8TB disk...as I said, you have nothing to loose now to try different approach. If FSTAB is now messy with the new disk addon, this will be maybe a solution to fix you file system with the disk 3 once the resync will perform
  7. may I make a suggestion to you here. If you plan is to upgrade your xpenology I suggest to shutdown your actual version remove your 4 disk array Put only your 8TB disk and install newest DSM but Don't create a volume with your 8tb disk shutdown your new dsm Put back your 4 disk array, and start your dsm. Let's see if you are now with a array (still degraded) but without filesystem corruption. as you said you got 99% of your data arleady saved into another backup, you have just 1% of possibility loosing stuff here.
  8. why didn't you just connected the new drive with usb and leaved in peace the previous work ? with a reboot you always be under risk of loosing something if you are already in trouble with bad disk or corrupted array. I don't understand the choice of btrfs for your spare job disk if it's just to recover your data and rebuild your crashed volume, in final term they will go back in your array isn't it ?
  9. I don't understand how you come from root@DiskStation:/volume1# cat /etc/fstab none /proc proc defaults 0 0 /dev/root / ext4 defaults 1 1 /dev/vg1000/lv /volume1 ext4 ro,noload,sb=1934917632,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,synoacl,relatime 0 0 to now root@DiskStation:/volume1# cat /etc/fstab none /proc proc defaults 0 0 /dev/root / ext4 defaults 1 1 /dev/vg1000/lv /volume1 btrfs 0 0 seems your new mounted volume take the place of your previous volume...but here you had choose btfrs instead of ext4 for the new volume disk added. maybe you will need to mount your previous volume into /volume2 I'm maybe wrong, but @flyride will give better check of my supposition as he said .: "you might have a new line in the file for your volume2/md3 that you should leave alone"
  10. Yep ! I don't want to miss the gate, first I will try to copy all outside, but this will take a wile (5,5To here) and I need to purshase a spare disk of 6To (not a good time for expense but if we need...) I can already tell you the btrfs check --init-extent-tree /dev/vg1000/lv gived in return parent transid verify failed on 394340270080 wanted 940895 found 940897 parent transid verify failed on 394340270080 wanted 940895 found 940897 parent transid verify failed on 394340270080 wanted 940895 found 940897 parent transid verify failed on 394340270080 wanted 940895 found 940897 Ignoring transid failure Couldn't setup extent tree extent buffer leak: start 394340171776 len 16384 Couldn't open file system is it lost doctor ?
  11. Yess! vgchange -ay give success and active now but only the mount -o recovery,ro /dev/vg1000/lv /volume2 the one without the file system had worked. I just being a test rsync between one of my folder to another basic nas mounted with nfs into volume 1, and apparently it goes well. Do you think there is a way to fix the file system from this volume , and then to be back again into my xpenology ? Thank You Flyride to have take time to come back to me, really appreciate.

  13. Hi @flyride do you mind you will have some time to help me too ? My volume is crashed but this one is not an ext4 but btrfs.

  14. Hello I'm reading this post with big hope as I'm in the same situation but with a RAID SHR1, this mean I got lv. but unfortunately the btrfs check -init-extent-tree /dev/vg1000/lv for me won't fix my issue. here is my result # btrfs check --init-extent-tree /dev/vg1000/lv parent transid verify failed on 394340270080 wanted 940895 found 940897 parent transid verify failed on 394340270080 wanted 940895 found 940897 parent transid verify failed on 394340270080 wanted 940895 found 940897 parent transid verify failed on 394340270080 wanted 940895 found 940897 Ignoring transid failure Couldn't setup extent tree parent transid verify failed on 394340270080 wanted 940895 found 940897 Ignoring transid failure Couldn't setup device tree extent buffer leak: start 394340171776 len 16384 extent buffer leak: start 394340171776 len 16384 Couldn't open file system I'm lost again like my data. @flyride do you have an idea why my don't want to be fixed ? thanks for advise and sorry to come into this post generated by @Mitt27 but his post is corresponding at 99% of my situation, but his solution apparently don't work with me.
  15. Check if your Win10 didn't disabled SMB1 protocols with some latest update. Once enabled again, you probably get some succes to reach your xpenology. Other way is to use the tools synology finder to map a shared folder to into your Win10.

  22. Hello. I'm trying to restore my btfrs volume2 but it seems to be not so easy, especialy for a newbee like me I followed some old post from this forum who gived some path to a solution but after many try and finaly doing a btfrs Dry run restore to check if i'm able to restore, but i'm still falling on some errors. Do I have obligation to pull out my 4 disk from my nas and connect it to a spare computer under a live CD ubuntu to get this restore/copy ? Before I purshase a new drive of 6TB to be able to receive the 5,5To data to restore, I want to be sure i can really restore my data from this crashed volume. Any help will be much appreciate, and a big Easter chocolate egg will be send to my angel keeper that will offer his knowledge and time to me ang give a solution to copy my data in another secure place.
  23. Hello. I'm facing the same problem than you, and looking for a solution from days now. Apparently you got ext4 for your file system, then it will be more easy to refund and mount your volume. Myn is a btfrs and is much more complicate as synology use his own btfrs repositery and this create some behavior to make the btfrs command work as expected. Can you make those commands and send back the result ? vpdisplay vgdisplay
  24. Nice ! What's about Plex and hardware transcoding ? Did you test and got success with it ?
