For future filesystem compatibility, we are wondering if there are any Lustre MDT filesystems in existence that have 2B or more total inodes? This is fairly unlikely, because it would require an MDT filesystem that is > 8TB in size (which isn''t even supported yet) and/or has been formatted with specific options to increase the total number of inodes. This can be ch...

In 1.6.0, when creating a MDT, you could specify multiple --mgsnode options and it would failover between them. 1.6.3 only seems to take the last one and --mgsnode=192.168.1.252 at o2ib:192.168.1.253 at o2ib doesn''t seem to failover to the other node. Any ideas how to get around this? Robert Robert LeBlanc College o...

Article by Jeff Layton: http://www.linux-mag.com/id/7839 anyone have views on whether this sort of caching would be useful for the MDT? My feeling is that MDT reads are probably pretty random but writes might benefit...? GREG -- Greg Matthews 01235 778658 Senior Computer Systems Administrator Diamond Light Source, Oxfordshire, UK

I''m evaluating lustre. I''m trying what I think is a basic/simple ethernet config. with MDT and OST on the same node. Can someone tell me if the following (~150 second recovery occurring when small 190 GB OST is re-mounted) is expected behavior or if I''m missing something? I thought I would send this and continue with the eval while awaiting a response. I''m using lustre...

Greetings Group! I hope this will be an easy one. To conserve steps in backing up the metadata extended attributes of a Lustre mdt, I am looking at using a newer version of tar combined with its --xattrs option. (Note: Previously I have used the mdt two-step back-up from the Lustre Manual and it has been successful.) If I can backup the extended attributes via tar so that I don''t have to issue both a getfattr and...

I''m a Lustre newbie who just joined this list. I''d appreciate any help on the following Lustre 2.4 issue I''m running into: Every time I mount the MDT, the mount appears to succeed but /var/log/messages contains the message: "LustreError: 11-0: lustre-MDT0000-lwp-MDT0000: Communicating with 0@lo, operation mds_connect failed with -11".

In PXELinux 4.06 (the vanilla version, not gpxelinux.0), I'm trying to use pxechn.c32 to call iPXE (undionly) with option 67 set to call an iPXE script. The relevant portion of my PXELinux config looks like this: LABEL MDT MENU LABEL ^B - MDT 2012 SP1 com32 pxechn.c32 APPEND undionly.kpxe -o 67.s=ipxe/mdt.ipxe However iPXE doesn't seem to get the option correctly, it goes into auto-boot mode instead of loading the script. I've tried with pxelinux.0 and pxechn.c32 from 6.01 with the same result. Also...

...into R date-time numbers (seconds since 1970-01-01). Unfortunately, when I cast the R date-time number into POSIXct format it seems to adjust silently by one hour to reflect daylight savings time, but I have been unable to suppress that behavior. (The problem is that the matlab date is already in MDT, and I don't want to have to write my own code to suppress the added hour only when local DST rules apply.) To use the example of the R date-time number 1340717324, this is the behavior I observe: > as.POSIXct(1340717324,origin='1970-01-01') [1] "2012-06-26 14:28:44 MDT"...

Running under Windows XP 64 bit, as.POSIXlt()/as.POSIXct() seem to think that US time zones (EST5EDT, MST7MDT) switched from daylight savings back to standard time on Oct 28, 2007, whereas the switch is actually on Sun Nov 04, 2007. Examples: > Sys.timezone() [1] "Mountain Daylight Time" > as.POSIXct("2007-10-30 12:38:47") [1] "2007-10-30 12:38:47 Mountain Daylight Time&q...

...may be in the documentation. If so, I missed it. If a site has multiple Lustre file systems, the documentation implies that there only needs to be a single MGS for an entire site (regardless of the number of file systems). However, I also know it is fairly common to have a combined MGS/MDT. So here are the questions. 1. If we are going to have several Lustre file systems, is there any reason not to create each one with its own combined MGS/MDT? 2. Can an MGS which is a combined MGS/MDT for one file system serve as the MGS for one or more other file systems where the MGS a...

Just checking to be sure this isn''t a known bug or problem. I couldn''t find a bz for this, but it would appear that tunefs.lustre --print fails on a lustre mdt or ost device if mounted with mmp.

Hi, The documentation warns about using smaller inodes than 512 bytes on the MDT. If I plan to use a stripecount of one (I have many small files), is it possible to use an inode size of 256 bytes and still use in-inode EAs for metadata ? Thanks /Jakob
