Hi Paolo,
I was looking for documentation on the limits of #controllers,
#channels, #targets, #LUNs, #disks in virtio-scsi, and couldn't find
any, so I thought I would create that documentation instead. I wonder
if you could check that the following is correct information. Also -
at the bottom of the email - a puzzling problem or bug.
At the libvirt level, we refer to virtio-scsi disks using:
<devices>
<controller type="scsi" index="0" model="virtio-scsi"/>
...
<disk device="disk" type="file">
<source file="disk.img"/>
<target dev="sda" bus="scsi"/>
<driver name="qemu" type="raw"/>
<address type="drive" controller="0" bus="0" target="0" unit="0"/>
</disk>
On the qemu command line, the controller becomes:
-device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x2
(For Q35, it would specify a PCIe bus and the address would also be a
bit different).
On the qemu command line, the disk becomes:
-drive file=disk.img,format=raw,if=none,id=drive-scsi0-0-0-0
-device
scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=1
In libvirt <address ... controller="0"> refers back to the
<controller index="0"/> element. You can add more than one
virtio-scsi controller, but each one takes a PCI slot, and the number
of PCI slots can be limited (or on Q35, there are no effective limits
but there are other architectural constraints).
In libvirt, <address ... bus="0"> refers to the virtio-scsi "channel".
The current virtio-scsi driver in qemu has a hard limit of 1 channel,
so you can only use bus="0" (or channel=0).
Open question: Will this limit ever be increased?
In libvirt, <address ... target="0"> refers to the virtio-scsi
"scsi-id" (internally in the driver called just ".id"). You can use
any target from 0 to 255 inclusive.
In libvirt, <address ... unit="0"> refers to the virtio-scsi "unit" ie
the SCSI LUN. You can use any LUN from 0 to 16383 inclusive.
Open question: What does the bus=scsi0.0 parameter mean?
The maximum number of drives on a single controller is therefore
256 * 16384 = 4194304.
However there are other limits to consider:
(1) qemu is limited by the number of files it can open (ulimit -n /
RLIMIT_NOFILE). On Fedora, this is 1024 (soft) or 4096 (hard),
although of course it may be increased.
(2) libvirt has trouble with > about 8000 drives
(https://bugzilla.redhat.com/1443066).
(3) The Linux kernel used to be limited to three letter drive names
(ie. up to /dev/sdzzz, or 18278 drives), but in modern kernels
this is no longer an issue.
(4) The Linux kernel is quite slow at enumerating drives. I couldn't
get past 4000 drives without hitting SCSI layer timeouts.
Not tested yet: Does hotplugging work on individual LUNs?
----------------------------------------------------------------------
Currently libguestfs puts each disk on a separate target (target=i
unit=0), and therefore has an effective limit of 255 disks (256 - 1
because the appliance uses a disk).
When I changed libguestfs to use LUNs instead of targets (target=0
unit=i), I got a peculiar bug. It looks like there is some kind of
race when enumerating the device, where /sys is populated before the
device is actually available. See the below boot log, and compare it
to the init code:
https://github.com/libguestfs/supermin/blob/master/init/init.c#L176
* fp = fopen ("/sys/block/sdab/dev", "r") succeeds at line 181
* we read major:minor from fp at line 230
* we mknod ("/dev/root",...) at line 245
* we mount ("/dev/root", "/root", "ext2"...) at line 262, which fails with
EINVAL
* shortly after that, kernel messages indicate that sdab has been
attached.
Rich.
