Re: [Linux-PowerEdge] BIOS legacy boot with BOSS controller card

I'm not Raoul, but here's how I PXE boot for BIOS and UEFI.
First, I used dnsmasq for DHCP, so obviously, adapt for other servers.
I have this in my config (replace tftp.example.com with your TFTP server
and 192.168.1.2 with its IP address - haven't set PXE up for IPv6 yet):
# EFI boot will set ARCH option (93)
dhcp-match=set:efi32,option:client-arch,6
dhcp-match=set:efi64,option:client-arch,7
tag-if=set:bios,tag:!efi32,tag:!efi64
# PXE boot
dhcp-boot=tag:efi64,shimx64.efi,tftp.example.com,192.168.1.2
dhcp-boot=tag:bios,bios/lpxelinux.0,tftp.example.com,192.168.1.2
dhcp-option-force=lan,209,pxelinux.conf
Then in my TFTP root, I have:
shimx64.efi # from shim-x64 RPM: /boot/efi/EFI/fedora/shimx64.efi
grubx64.efi # from grub2-efi-x64 RPM: /boot/efi/EFI/fedora/grubx64.efi
EFI/fedora# from grub2-efi-x64-modules RPM: /usr/lib/grub/fedora
bios/ldlinux.c32 # from syslinux-tftpboot RPM: /tftpboot/ldlinux.c32
bios/libutil.c32 # from syslinux-tftpboot RPM: /tftpboot/libutil.c32
bios/lpxelinux.0 # from syslinux-tftpboot RPM: /tftpboot/lpxelinux.0
bios/menu.c32 # from syslinux-tftpboot RPM: /tftpboot/menu.c32
# local configs
grub.cfg
source (http,tftp.example.com)/local/grub2.cgi
bios/pxelinux.conf
ui menu.c32 http://tftp.example.com/local/pxe.cgi
I load the rest over HTTP from the same server; so much faster and more
reliable than TFTP, and the configs can be auto-generated this way. The
referenced CGIs generate configs like:
grub2.cgi:
terminal_input console
loadfont /12x26.pf2
insmod gfxterm
set gfxmode=auto
terminal_output gfxterm

Re: [Linux-PowerEdge] RHEL 8.x dell-system-update RPM should include libssh2 RPM as a dependency...
[EXTERNAL EMAIL] libssh is a completely different library from libssh2, so that's not going to work. libssh2 has been deprecated in RHEL 8.1 in favor of libssh - libssh2 _may_ get added to EPEL, but it has not so far. Dell should probably look at either updating their code to use the alternate, or they could include libssh2 in their RHEL 8 repo.

Right now, I just have the repos created manually with Ansible tasks. I didn't realize the key had changed (hadn't updated Dell stuff on a server yet).

I haven't tried UEFI PXE booting a Dell server, but I have done it with some random (non-Dell) other devices at home: notebooks, a desktop, and an Intel NUC. Everything worked fine except the NUC, and IIRC it was similar behavior to what you describe (but it has been a little bit so I can't remember now). It's possible that the same core Intel code is in the NUC and the Dells and has the same problem.

Yes, I'm tracking that, and there are no drops at the switches (or the Linux servers' end). The link utilization is pretty low. The server 1G ports are typically only running about 5-20 Mbps on each link (a spike is 50-100 Mbps on each, and those are usually only on one server at a time, hosting a busier VM). The SAN 10G ports are running about 30-50 Mbps (spiking to maybe 200 Mbps). My monitoring system is pulling stats from the switch every 60 seconds. I could reproduce some of the latency on a server in maintenance mode, where my script was the only thing touching the disk (so no other storage traffic from that server). > When you get high latency, does it affect only that node or all at the same > time? In that case, do you have pause frames on and are they being triggered? > Is there a spike in traffic at that moment (that second)? It seems to affect multiple nodes at the same time, although not always (or at least not always to the same extent). Usually, the oVirt warnings about high latency are only on one node at any given time (but there has been a time or two where it has been two nodes). Looking at pause frame stats on the switch, they're essentially zero (0-100 pause frames received on some server ports with a switch uptime of 5 months). No pause frames on the SAN ports, and no pause frames transmitted on any port from the switch. > Is there any packetloss between your hosts and your eql(s) ?

Re: [Linux-PowerEdge] EqualLogic, Linux, and latency
I hadn't thought of trying that... it does look like I still see occasional high read latency (100+ ms); I haven't seen the 1+ second (but that's sporadic anyway). Interestingly, it seems to only get higher latency on the logical volumes; just reading the first block of the iSCSI device (e.g. /dev/sdf) seems to consistently be under 1ms. Just to explain the setup (for those not familiar with oVirt): when you create a storage domain on an iSCSI device, oVirt sets up a Linux volume group on it, and then creates several internal-use logical volumes (including the "metadata" LV that I'm reading). After that, each virtual disk gets an LV create as well. The network _shouldn't_ be a problem (famous last words); the servers each have two 1G ports to a pair of N3000 switches for the storage network, and the SAN has 10G ports (but each 10G port is under 100 megabits per second most of the time). There's also an FS7600 with 1G ports talking to the same SAN. I'm going to install SAN HQ to get a better look at the SAN-side performance (but I've got to order a copy of Windows for that, bleh!).

[Linux-PowerEdge] EqualLogic, Linux, and latency
I have a stack of PowerEdge servers, running CentOS 7 and oVirt (virtualization environment), using an EqualLogic PS6610 for VM storage. I'm using the regular Linux multipath daemon, not the Dell kit, because oVirt manages the multipathing (and doesn't handle the Dell kit). I am periodically seeing high latency from the SAN, even from a host not running any VMs. I see 100+ ms reads, and sometimes even multi-second reads (to read a single 4K block). oVirt logs warnings about this; I wrote a simple perl script that duplicates what oVirt does (open a metadata logical volume block device with O_DIRECT, read a 4K block, and close it), and I see the same thing. I've got iscsid and multipathd configured per the recommended values, and I'm not seeing any issues on Linux or at the switches (dedicated network for iSCSI); it would seem to be something on the SAN itself. The SAN isn't reporting anything though, so I'm not sure what to look at.

[Linux-PowerEdge] A little OT: Dell EqualLogic FS series
This is a little off-topic, but is anybody familiar with the EqualLogic FS series NAS? They do appear to run CentOS, so it has some relevance here, right? I got an FS7600 for a setup that needs NFS (to be connected to a PS4100). Out of the box, one controller had a bad hard drive (couldn't mount root FS), so we got a replacement controller from Dell. However, the replacement controller has an older firmware rev. Each of these conditions keep me from creating the NAS cluster, because you have to add in matched pairs. I've been round and round will Dell support, trying to get a working setup, but I'm not getting anywhere. I'm trying to get that escalated now (not a problem with the tech on my case, but he doesn't seem to be getting good support from his level-2), but I'm just curious if anyone else is familiar with the workings of the FS series and might have any ideas (this is my first FS box). -- Chris Adams <li...@cmadams.net> ___ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge
Re: Consistent Network Device Naming for LOMs coming...
Once upon a time, Sean Dilda s...@duke.edu said: I can't remember the last box I setup with non-onboard NICs. As such, I think naming the on-board NICs differently from PCI NICs is just going to lead to needless confusion. aolme too/aol Under some OSes, ethernet device names vary depending on the driver and such, but Linux has always named all wired ethernet devices ethX. Some wireless get different names, but I can't remember running into any wired devices being anything other than ethX. It is rather late in the game to change that. -- Chris Adams cmad...@hiwaay.net Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. ___ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
Re: Consistent Network Device Naming for LOMs coming...
Once upon a time, Matt Domsch matt_dom...@dell.com said: Folks, without kernel-side changes which have been rejected, changes that reserved the first N ethX names for on-board devices, we cannot simply swizzle the names within the ethX namespace using udev rules. I wish that weren't true. Hmm, I thought the Fedora/RHEL initscripts had been renaming eth* devices around for year; is that broken? I guess to me, it would be better to spend time fixing the kernel ordering to follow the motherboard, rather than spend time creating tools to rename some NICs, make sure other tools can handle the new names, etc. -- Chris Adams cmad...@hiwaay.net Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. ___ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
Re: CentOS 5.5 - Deleted Partition
Once upon a time, Brian McGrew br...@visionpro.com said: I guess it¹s too early to be up on a Saturday because I just made the biggest newbie blunder of my career. I got my hands crossed, grabbed the wrong terminal and deleted /dev/sdb1 with fdisk from a mounted, production volume. This volume is still accessible and mounted through LVM (/dev/mapper/VolGroup00-LogVol00) and all the data is still accessible. Noting appears to be missing. But, if I do an fdisk l on /dev/sdb, I have no partitions listed. The kernel won't re-read the partition table if there are open partitions, so whatever you do, DON'T REBOOT (it'll be gone then). Do you know the particulars of the old partition table? If so, just re-run fdisk and recreate the partition(s) to match. If not, I'm not sure if there is a way to see what the running kernel thinks the partition table looks like. -- Chris Adams cmad...@hiwaay.net Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. ___ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
Re: Preventing I/O starvation on MD1000s triggered by a failed disk.
Once upon a time, Bond Masuda bond.mas...@jlbond.com said: Do you know if you encountered a URE? I've been running into URE's on large RAID-5 arrays that use 500GB, 750GB, 1TB drives... basically, RAID-5 might survive a single disk failure, but the rebuild will kill it due to URE. In this situation, usually you can force online the disk that had the URE and still be able to read data in degraded state as long as you avoid the block that has the URE. If URE is the issue, then you should start considering RAID-6. I assume you are talking about the case where one drive in a RAID-5 fails, and while rebuilding, a bad block is discovered on another drive (which results in at least that block being unrecoverable, and possibly turning the whole array offline, depending on the RAID controller). Linux software RAID has a way to validate an array. Newer RHEL and Fedora (and others I expect) run this check weekly and report any faults. Is there a way to do the same thing on the hardware RAID controllers (either internal cards or external arrays like EqualLogic)? -- Chris Adams cmad...@hiwaay.net Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. ___ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
