I have some problems with a SAN here. Don't know if the problems= =20 lies in scsi code/driver or other thing... The setup is : a QLA2300 (Fibre channel) with 6.0.64 driver from qlogic site, 2.4.26 kernel, device mapper 1.0.17 applied, and xfs or reiserfs on top of lvm volumes (using evms) This setup seemed fine since some months now, with giga of data moved=20 every day, but I noticed this on the log: Jun 22 16:45:15 talisker kernel: SCSI disk error : host 3 channel 0 id = 2=20 lun 1 return code =3D 20000 Jun 22 16:45:15 talisker kernel: I/O error: dev 08:10, sector 14542331= 2 I have two of these errors in the last month. What's the meaning of thi= s=20 return code ? I made badblock on the /dev/evms volume, and all is OK. I also performed a disk scan on the raid array, (an IFT 7250F) and ther= e=20 are no errors. The machine can be quite heavily loaded. May I suspect the qla driver ?= =20 May I suspect the underlying LVM. The LVM has been resized by the=20 past... Can an error happens here too ? I'm very puzzled... This is just a summary . I can furnish more information if needed. --=20 Yann Dupont, Cri de l'universit=E9 de Nantes Tel: 02.51.12.53.91 - Fax: 02.51.12.58.60 - Yann.Dupont@univ-nantes.fr - To unsubscribe from this list: send the line "unsubscribe linux-scsi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
