Do you mean /dev/rsd2c? As I understand it, if I left the name that's in the document, /dev/rsd0c I would screw all data of my internal drive, where the OS is installed. sd2 is what I got from dmesg 2016-05-25 12:47 GMT+02:00 Raf Czlonka : > On Tue, May 24, 2016 at 05:10:31PM BST, Pau Amaro-Seoane wrote: >> Dear all, >> >> I have been following this guide here: >> >> http://www.openbsd.org/faq/faq14.html#softraidCrypto >> >> And I get this problem: >> >> pyrrha# dd if=/dev/arandom of=/dev/rsd2c bs=1m > ^ > Since there's no difference on OpenBSD, why do you keep on changing > the device name to something other than what's in the document? > >> dd: /dev/rsd2c: short write on character device >> dd: /dev/rsd2c: end of device >> 57260+0 records in >> 57259+1 records out >> 60040544256 bytes transferred in 2966.279 secs (20241028 bytes/sec) >> pyrrha# fdisk -iy sd2 >> Writing MBR at offset 0. >> pyrrha# disklabel -E sd2 >> Label editor (enter '?' for help at any prompt) >> > a a >> offset: [64] >> size: [117258371] >> FS type: [4.2BSD] >^^^ > This should be RAID. > > It is there in the document you had linked to above :^) > > Regards, > > Raf > >> Rounding size to bsize (32 sectors): 117258368 >> > w >> > q >> No label changes. >> pyrrha# bioctl -c C -l sd2a softraid0 >> softraid0: invalid metadata format >> >> /dev/sd2 is my external usb disk. >> >> What am I doing wrong? >> >> Thanks, >> >> Pau >> ___ >> Openbsd-newbies mailing list >> Openbsd-newbies@sfobug.theapt.org >> http://mailman.theapt.org/listinfo/openbsd-newbies > ___ > Openbsd-newbies mailing list > Openbsd-newbies@sfobug.theapt.org > http://mailman.theapt.org/listinfo/openbsd-newbies ___ Openbsd-newbies mailing list Openbsd-newbies@sfobug.theapt.org http://mailman.theapt.org/listinfo/openbsd-newbies
