stevebakerjanders: yeah, its regarding physical vs logical sector size. sgdisk deals in sectors, but is ambigious about which it uses https://linux.die.net/man/8/sgdisk01:21
stevebakerjanders: right now I'm assuming physical, and getting it from /sys/block/sda/queue/physical_block_size01:22

jandersstevebaker noted01:29
jandersstevebaker what are you using this info for?01:29
stevebakerjanders: creating a partition from empty space, then using that for an LVM physical volume01:30
jandersstevebaker I'll spin up an OpenStack VM with a volume attached and have a look around01:30
stevebakerjanders: on my dell the physical and logical are both 512, which isn't much help01:31
jandersstevebaker what OS are you using (just so my testing is relevant)?01:31
stevebakerjanders: rhel-8.201:38
jandersI've got CentOS8.2, should be close enough01:38
jandersSector size (logical/physical): 512/512 bytes01:40
janderssame situation01:40
*** k_mouza has joined #openstack-ironic01:42
janderswould other units (MB, MiB) be any use for this purpose?01:42
jandersor is this to do with alignment with sectors?01:42
stevebakerjanders: I've decided to use sgdisk rather than parted because it can just tell you the largest unpartitioned space (in sectors) which is very convenient01:45
jandersright!01:46
jandersnow I get where the sectors come from01:46
*** dsneddon has quit IRC01:46
*** k_mouza has quit IRC01:46
stevebakerthen I convert to bytes for the rest, except LVM deals with physical volume extents, which are 4MiB bit01:47
stevebakerbig01:47
jandersSector size (logical/physical): 512/4096 bytes01:49
jandershah I found a piece of HW that doesn't have the same logical and physical size01:50
janderswould this be useful to determine which value sgdisk uses?01:50
janders(this must be one of those mythical Advanced Format drives)01:51
stevebakercool01:51
stevebakerjanders: first can you cat  /sys/block/sda/queue/physical_block_size and  /sys/block/sda/queue/logical_block_size01:52
jandershttp://paste.openstack.org/show/805369/ < no surprises01:52
stevebakerjanders: then: sgdisk --print /dev/sda01:53
stevebakershows sectors and size01:54
jandershttp://paste.openstack.org/show/805370/01:54
jandershttp://paste.openstack.org/show/805371/01:55
janders^ bonus, an empty drive for testing :)01:55
janderssome SATA SSDs from the look of it01:55
jandersyeah rotational=0 so certainly (it was quite obvious from the name :) )01:56
stevebakerjanders: its logical size!01:56
janders\o/01:57
jandersso - more portability?01:57
janders(it seems logical sector size is quite consistent across different drives)01:57
stevebakerhmm, yes that makes sense01:58
janderswould it be useful for you to get access to this machine?01:59
jandersor is this info sufficient?01:59
stevebakerjanders: thats all I need, I've switched to reading logical_block_size02:00
stevebakerjanders: here is what I'm working on https://review.opendev.org/c/openstack/diskimage-builder/+/79108302:00
stevebakerjanders: specifically this script https://review.opendev.org/c/openstack/diskimage-builder/+/791083/2/diskimage_builder/elements/growvols/static/usr/local/sbin/growvols02:00
jandersstevebaker handy! great work02:01
jandersI will go get some lunch now, but happy to help further a bit later02:03
stevebakerjanders: thanks for the help, I might ask you to try it out when I've done a bit more of the dib stuff, I think the script works now02:03
jandersno worries, I will have those SuperMicros for some more time so just let me know when ready02:04
jandersalthough this physical layout has probably more to do with the SSDs than anything else (NVMes don't seem to have that)02:06
stevebakerok thanks02:19

*** derekh has joined #openstack-ironic08:10
iurygregoryajya, we saw something strange in another cluster when doing the deployment, iDRAC is trying to mount the remote share in the ipv6 address from one of the interfaces of the node http://paste.openstack.org/show/805376/08:24
iurygregorythis would be expected?08:24
iurygregoryI have no idea what address iDRAC should use when mounting the remote share =)08:24
*** rcernin has quit IRC08:32
ajyaiurygregory: not expected, that URL is provided by Ironic, it's input parameter here https://opendev.org/openstack/ironic/src/branch/master/ironic/drivers/modules/redfish/boot.py#L180 and generated somewhere in this file - https://opendev.org/openstack/ironic/src/branch/master/ironic/drivers/modules/image_utils.py#L39408:37
ajyaneed to trace why it gets ipv608:38
iurygregoryajya, oh ok, so it would be the location from the iso (if is hosted under ipv6 it would be correct)08:39
iurygregoryhumm I'm wondering if /redfish/boot-bbbcace4-5a16-4d7a-bc83-5f309ca74457.iso?filename=tmpq_qmh276.iso is something that would work ...08:40
ajyafrom BMC? I don't think so, that's the file outside of BMC08:41
ajyathe file is served by conductor, currently I don't see how this is related to iDRAC, it's more like conductor config08:42
*** mgoddard has quit IRC08:43
*** mgoddard has joined #openstack-ironic08:43
iurygregoryyeah, maybe some config problem08:44
ajyaby default virtual media boot uses swift, that's controlled by [redfish]use_swift, this does not look like swift URL, so it's standalone HTTP server, that I think is controlled by [deploy]http_url, but double check in the code08:52
ajyaipv6 could be fine as such (is it expected to use ipv6?), but then that's another issue why it can't access it over ipv608:54
ajyaalso, non-standard port is in use, and there is this known issue with it - https://docs.openstack.org/ironic/latest/admin/drivers/idrac.html#unable-to-mount-remote-share-with-idrac-firmware-4-40-00-00-or-newer08:55
iurygregoryit's standalone ironic =)08:59
iurygregoryno swift :D08:59
iurygregoryajya, what should be the default port?09:00
ajyaiurygregory: I'd say keep the port you need, but make sure that eHTML5 plugin type is not in use09:01
iurygregoryI know about the HTML5 for the plugin (they changed after doing the upgrade on the FW, before trying to deploy)09:01
ajyaok, then it's not the port09:01
iurygregoryI will try to get access to the setup to look at ironic logs for more information09:02
ajyaThere was some config added recently around this, I think Dmitry did it, maybe that's needed09:07
ajyameant this - https://review.opendev.org/c/openstack/ironic/+/78276009:09
iurygregoryoh I see09:11
