[Xen-users] Virtual disk on physical partition of second drive
NetBSD 3.99.12 domain0 and domainUs: After creating several domainU''s on my first drive, sd0, I''m trying to create domains on a second drive, sd1, and encountering surprises. sd1 is partitioned: domain0# disklabel sd1 # /dev/rsd1d: type: SCSI disk: mydisk label: fictitious flags: bytes/sector: 512 sectors/track: 705 tracks/cylinder: 4 sectors/cylinder: 2820 cylinders: 50824 total sectors: 143374744 rpm: 15015 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # microseconds track-to-track seek: 0 # microseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize cpg/sgs] c: 143374681 63 unused 0 0 # (Cyl. 0*- 50842*) d: 143374744 0 unused 0 0 # (Cyl. 0 - 50842*) e: 35830920 63 4.2BSD 2048 16384 28760 # (Cyl. 0*- 12706*) f: 35830920 35830983 4.2BSD 2048 16384 28760 # (Cyl. 12706*- 25412*) g: 35830920 71661903 4.2BSD 2048 16384 28760 # (Cyl. 25412*- 38118*) h: 35830920 107492823 4.2BSD 2048 16384 28760 # (Cyl. 38118*- 50824*) I''m trying to install domain "proxy". In it''s config file I have: disk = [ ''phy:/dev/sd1e,sd0d,w'' ] root = "/dev/sd0d" I am unable to partition xb0. Looking into it, it appears that xb0 is sd1 rather than sd1e: # disklabel xbd0 # /dev/rxbd0d: type: SCSI disk: mydisk label: fictitious flags: bytes/sector: 512 sectors/track: 705 tracks/cylinder: 4 sectors/cylinder: 2820 cylinders: 50824 total sectors: 143374744 rpm: 15015 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # microseconds track-to-track seek: 0 # microseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize cpg/sgs] c: 143374681 63 unused 0 0 # (Cyl. 0*- 50842*) d: 143374744 0 unused 0 0 # (Cyl. 0 - 50842*) e: 35830920 63 4.2BSD 2048 16384 28760 # (Cyl. 0*- 12706*) f: 35830920 35830983 4.2BSD 2048 16384 28760 # (Cyl. 12706*- 25412*) g: 35830920 71661903 4.2BSD 2048 16384 28760 # (Cyl. 25412*- 38118*) h: 35830920 107492823 4.2BSD 2048 16384 28760 # (Cyl. 38118*- 50824*) Displaying the disklabel for another domain that uses: disk = [ ''phy:/dev/sd0h,sd0d,w'' ] root = "/dev/sd0d" shows that the virtual block device is using the partition: imap# disklabel xbd0 # /dev/rxbd0d: type: unknown disk: Xen Virtual ESD label: flags: bytes/sector: 512 sectors/track: 2048 tracks/cylinder: 1 sectors/cylinder: 2048 cylinders: 14055 total sectors: 28786560 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # microseconds track-to-track seek: 0 # microseconds drivedata: 0 16 partitions: # size offset fstype [fsize bsize cpg/sgs] a: 262144 0 4.2BSD 1024 8192 32768 # (Cyl. 0 - 127) b: 4194304 262144 swap # (Cyl. 128 - 2175) c: 28786560 0 unused 0 0 # (Cyl. 0 - 14055*) d: 28786560 0 unused 0 0 # (Cyl. 0 - 14055*) e: 12582912 4456448 4.2BSD 2048 16384 26992 # (Cyl. 2176 - 8319) f: 4194304 17039360 4.2BSD 2048 16384 21848 # (Cyl. 8320 - 10367) g: 7552896 21233664 4.2BSD 2048 16384 28880 # (Cyl. 10368 - 14055*) Why the difference between sd0 and sd1?
