Re: BTRFS RAID filesystem unmountable

I have let the find root command run for 14+ days, its produced a pretty huge log file 1.6 GB but still hasn't completed. I think I will start the process of reformatting my drives and starting over. Thanks for your help anyway. Kind regards Michael On 5 May 2018 at 01:43, Qu Wenruo

Hi Qu, The tool is still running and the log file is now ~300mb. I guess it shouldn't normally take this long.. Is there anything else worth trying? Kind regards Michael On 2 May 2018 at 06:29, Michael Wade wrote: > Thanks Qu, > > I actually aborted the run with the old

Re: BTRFS RAID filesystem unmountable

Thanks Qu, I actually aborted the run with the old btrfs tools once I saw its output. The new btrfs tools is still running and has produced a log file of ~85mb filled with that content so far. Kind regards Michael On 2 May 2018 at 02:31, Qu Wenruo wrote: > > > On

Hi Qu, Oh dear that is not good news! I have been running the find root command since yesterday but it only seems to be only be outputting the following message: ERROR: tree block bytenr 0 is not aligned to sectorsize 4096 ERROR: tree block bytenr 0 is not aligned to sectorsize 4096 ERROR: tree

Re: BTRFS RAID filesystem unmountable

Ok, will it be possible for me to install the new version of the tools on my current kernel without overriding the existing install? Hesitant to update kernel/btrfs as it might break the ReadyNAS interface / future firmware upgrades. Perhaps I could grab this:

Re: BTRFS RAID filesystem unmountable

Hi Qu, Thanks for your reply. I will investigate upgrading the kernel, however I worry that future ReadyNAS firmware upgrades would fail on a newer kernel version (I don't have much linux experience so maybe my concerns are unfounded!?). I have attached the output of the dump super command. I

Hi all, I was hoping that someone would be able to help me resolve the issues I am having with my ReadyNAS BTRFS volume. Basically my trouble started after a power cut, subsequently the volume would not mount. Here are the details of my setup as it is at the moment: uname -a Linux QAI
