hi, because there are so many "help"/"didn't work" mails here, I want to give positive feedback: Reshape of a 4-disk RAID6 (250GB each) to RADI5 worked perfectly, now having a 3-disk RAID5 + hot spare. the backup-file was on a NFS4-share ;) duration: ca. 26h (cannot say for sure, it finished during night) alas, I'm not able to tell the max. filesize of the backup-file (mdadm deletes it afterwards), but when I looked at it in the middle of the process, it was about 30MB. Unlike what I excpected from the man-page, I had network traffic during the *whole* reshape-process, not just at the beginning. It would be interesting to know, how fast the reshape process would have been, if the backup-file were on a local disk... kernel-2.6.36 mdadm-3.1.4 thank you very much for all the good work and user support on this list!! cheers, florian -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
