A lot of NILFS: bad btree node messages (readonly fs)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello.

Doing some work today (system update, kernel update, rsync rootfs with
external drive) I noticed some unwanted behaviour:
maszn ~ # touch afile
touch: cannot touch ‘afile’: System plików wyłącznie do odczytu
                        it's Read only filesystem

dmesg shows a lot (1812 in the log) of:
[ 8288.319012] NILFS: bad btree node (blocknr=26229286): level = 178,
flags = 0x0, nchildren = 0
[ 8288.319017] NILFS error (device sda2): nilfs_bmap_lookup_contig:
broken bmap (inode number=102230)

After mount -o remount,rw /
[ 8384.734024] segctord starting. Construction interval = 300 seconds,
CP frequency < 30 seconds
[ 8384.734028] NILFS warning: mounting fs with errors

Never happend before and it looks like it works fine now (using vanilla
kernel 3.6.4).

After a reboot (to vanilla kernel 3.6.8) dmesg shows:
[    6.046883] segctord starting. Construction interval = 300 seconds,
CP frequency < 30 seconds
[    6.046884] NILFS warning: mounting fs with errors

I don't like the "errors" part...
