[Bug 535939] New: wrong calculation with virtual_gb and sector_size options in scsi_debug
http://bugzilla.novell.com/show_bug.cgi?id=535939 Summary: wrong calculation with virtual_gb and sector_size options in scsi_debug Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Minor Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: aschnell@novell.com QAContact: qa@suse.de Found By: Development When using a sector_size for scsi_debug different from the default 512B the size of the resuling disk is wrong. Disk size with default sector size: thalassa:~ # modprobe scsi-debug num_tgts=1 virtual_gb=1 thalassa:~ # grep sdc /proc/partitions 8 32 1048576 sdc Disk size with sector size 4kB: thalassa:~ # modprobe scsi-debug num_tgts=1 sector_size=4096 virtual_gb=1 thalassa:~ # grep sdc /proc/partitions 8 32 8388608 sdc -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

http://bugzilla.novell.com/show_bug.cgi?id=535939 http://bugzilla.novell.com/show_bug.cgi?id=535939#c1 --- Comment #1 from Jeff Mahoney <jeffm@novell.com> 2009-12-19 17:50:02 UTC --- Created an attachment (id=333560) --> (http://bugzilla.novell.com/attachment.cgi?id=333560) scsi_debug: scale virtual_gb with sector_size properly[PATCH] Patch-mainline: Probably 2.6.33; Acked on linux-scsi 17 Dec 2009 The scsi_debug virtual_gb feature currently assumes that the sector size is always 512 bytes and scales virtual_gb based on that assumption. When passed a different sector size, the capacity of the disk is scaled incorrectly higher than it should be. For example, modprobe scsi_debug virtual_gb=1 sector_size=4096 results in an 8 GB device. This patch scales it appropriately.

Closing as FIXED. The SLE11 fix also fixes an issue with scsi_debug devices larger than 1 TB. That fix was added to mainline in 2.6.31, so it was included in 11.2 and master automatically. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
