Hello. My nilfs suddenly become read-only. I saw these logs in /var/log/messages: Dec 19 11:20:05 localhost kernel: NILFS: bad btree node (blocknr=710153406): level = 0, flags = 0x2, nchildren = 25088 Dec 19 11:20:05 localhost kernel: NILFS error (device sdb2): nilfs_bmap_lookup_contig: broken bmap (inode number=321775) Dec 19 11:20:05 localhost kernel: Dec 19 11:20:05 localhost kernel: Remounting filesystem read-only Dec 19 11:20:05 localhost kernel: NILFS: bad btree node (blocknr=710153406): level = 0, flags = 0x2, nchildren = 25088 Dec 19 11:20:05 localhost kernel: NILFS error (device sdb2): nilfs_bmap_lookup_contig: broken bmap (inode number=321775) Dec 19 11:20:05 localhost kernel: Dec 19 11:20:05 localhost kernel: NILFS: bad btree node (blocknr=710153406): level = 0, flags = 0x2, nchildren = 25088 Dec 19 11:20:05 localhost kernel: NILFS error (device sdb2): nilfs_bmap_lookup_contig: broken bmap (inode number=321775) Dec 19 11:20:05 localhost kernel: Dec 19 11:20:05 localhost kernel: NILFS: bad btree node (blocknr=710153406): level = 0, flags = 0x2, nchildren = 25088 Dec 19 11:20:05 localhost kernel: NILFS error (device sdb2): nilfs_bmap_lookup_contig: broken bmap (inode number=321775) Dec 19 11:20:05 localhost kernel: …………………………………………………… How can I fix this? There is 6TiB data on my disk, I don't want to format the disk. I found that a lot of people have encountered the same problem. Is this a bug of nilfs? How can I avoid this problem? When it happens, I was running multiple MySQL and rsync, and nilfs_cleanerd was cleaning segments.
