In a very first attempt, my disk:2 was partitioned and initialized as follows:
/dev/sdc1 1,5TB NTFS /dev/sdc2 0,5TB EXT4
This was later changed to what you can see below and what fdisk correctly reports. These partitions all use the EXT4 file system.

I'm wondering why lshw and parted shows some of the partitions still being NTFS volumes? Checkout the output below. How can this be fixed? What is missing? Erase some header data?

Probably. I make it a habit to clean the first few Mebibytes (and, recently, also the last few Mebibytes) of a partition before (re-)using it (and also using in the first place).
ReplyDeleteAdditionally… 0xFD Linux RAID autodetect works only with 0.90 metadata, which recently made my system unbootable (because it was on the last partition, which made md think the RAID is on /dev/sda instead of /dev/sda2); you should be using 0xDA arbitrary data and 1.x metadata… ☹
That seems to work. sfdisk even showed some message (I probably overlooked before) to run: dd if=/dev/zero of=/dev/sd?? bs=512 count=1.
DeleteI have no problem with version 1.2 metadata (I don't use the RAID to boot from it) although there seems to be an issue: http://article.gmane.org/gmane.user-groups.linux.dresden/23580.
Partition tables do contain a flag to specify the filesystem type of a partition. Best bet: the partition still has a flag value matching ntfs. You can correct the situation using cfdisk. Be sure to read the manual before using this command. HTH
ReplyDeleteNeither cfdisk nor parted were able to delete this flag. I got it using the command issued by sfdisk: dd if=/dev/zero of=/dev/sdc1 bs=512 count=1
