[OpenAFS] Strange kernel messages from yesterday...

[Claudio Prono]

Hello all,

I have seen some strange errors into my dmesg. The system is an OpenSuse
11.0 with openafs-1.4.8-3.1.

That are the errors:

REISERFS warning (device cciss/c0d2p1): journal-d1 flush_commit_list:
jl->j_len = 0; jl->j_state = 0; jl->j_trans_id = 0; jl->j_refcount = 0;
journal->trans_id = 1744730; oldest live jl->j_trans_id = 1742447

Btw there is no phisical problem with the disks, as reported with the HP
smartarray utility:

cciss_vol_status -q /dev/cciss/c0d2
/dev/cciss/c0d2: (Smart Array 5i) RAID 5 Volume 0(?) status: OK.
/dev/cciss/c0d2: (Smart Array 5i) RAID 5 Volume 1(?) status: OK.

I have to start to worry about it or is simply an openafs bug?

Cordially,

Claudio.
