--- Comment #5 from Andrey V. Elsukov <a...@freebsd.org> --- (In reply to Tomasz "CeDeROM" CEDRO from comment #3) > 1. I would like to clarify why I was unable to write to MBR (first 512 bytes) > of the da1 while there was no problem with writhing to the rest of the disk? How did you know that? Did you compare the first 512 bytes on both disks after copying? > 2. GEOM_PART: integrity check failed (da1, MBR) <- could that block / discard > writes to MBR silently? This usually means that parition table's metadata is wrong. If it is wrong, and kern.geom.part.check_integrity is set, then GEOM_PART just ignores the partition table. > 3. Why `dd if=/dev/da0 of=/dev/da1` did copy all disk except the MBR? How did you know that? Did you compare the first 512 bytes on both disks after copying? I assume you have disks with different size and GEOM_PART just rejects MBR on the copied disk, because its integrity check has failed. > 4. Why I was unable to write to MBR from a file but it was possible to write > that data from a file over md0? Again, how did you know that? -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-geom@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-geom To unsubscribe, send any mail to "freebsd-geom-unsubscr...@freebsd.org"
