Re: [PATCH] Btrfs: add another missing end_page_writeback on submit_extent_page failure

Thanks for your reply. I think you mentioned about the below if-block in __extent_writepage(). if (nr == 0) { /* make sure the mapping tag for page dirty gets cleared */ set_page_writeback(page); end_page_writeback(page); } However, this if-block only works when nr is

btrfs receive leaves new subvolume modifiable during operation

I have been testing btrfs send/receive. I like it. During those tests I discovered that it is possible to access and modify (add files, delete files ...) of the new receive snapshot during the transfer. After the transfer it becomes readonly but it could already have been modified. So you can

Re: btrfs recovery - solved for me

Michael, That's great news. Well done. ext4 works just fine for most cases. If you wish to experiment I might suggest more work on your part (just what you need, right?) by using btrfs for smaller file systems (perhaps just root, maybe /var, /bin etc.) but try installing zfs for large file

Re: btrfs recovery - solved for me

Thank you all for your help. Magically, btrfs-find-root worked today. (I attached the steps at the end) I don't think I changed anything. The btrfs-progs version is still 4.1 because I tried different tagged versions (starting from 4.9) from the cloned git repo. The btrfs-find-root on the
