FYI, unless you have to dual boot with windows, you should avoid using fakeraid and stick with conventional linux software raid, which is much better supported. > sdb and sdc are the RAID members here and the RAID device is > md126. Then you need to only manipulate md126 and ignore sdb and sdc. Most of what you seem to be reporting involves looking directly at the individual disks, which you must not do as that will present a partial/corrupt view of the raid array. In other words, if the first few sectors of the raid array map to sdb, then sdb will appear to have a partition table in its sector 0 that describes a disk that is twice the size, since this partition table is actually describing the raid array and not the individual disk. The one thing you mention that I can't write off as user error is "but parted is not and seems to be forcibly applying what it believes to be correct (ignoring the fact that it was only asked to display info, not modify anything)". Can you provide more details here? Exactly what command did you run and what changed before vs. after? Parted should not be modifying anything on the disk unless you tell it to. Normally it will throw a warning telling you something is wrong with the disk and ask if you want it to fix it and you have to answer "fix" for it to modify the disk. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) iQEcBAEBAgAGBQJU5QWEAAoJENRVrw2cjl5RwnkH/0jvimRzKxUZjFait+KVZQgW gq2m6MVJYiDZLX3ajGZj2mxQNVu2RFqDn+YwqAWeDtrQEj/B0TXJC3RbBJpoN3Ao 5kH+lU2Z+YihRDpQMst8VGt1MVA6izcapN1uVeJOcLB2wICSGd0WcjAn8ROSnZNS o/7hXLh7dhxQZT+2HsTpmWa6pLEVvyBeQ8u2giNB0w8he75qv4/AxCFYAdVqhr4Y nNfC9zzCtcOGExu12GyigEpWUPlxUcyGsYzaQRR2hG1Vv7LKBsDBsok3qAag033E DyhyCWDj8NJk1WQIW2ZyVjhcskSyl59Oatd7X3TGSqr2L7yaHV+QAA5Cng+A9fw= =WuvR -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
