From 49098da02b3a9ef20481295699cac6f7ae6fe452 Mon Sep 17 00:00:00 2001 From: Matt Ezell Date: Wed, 5 Feb 2014 00:23:26 -0500 Subject: [PATCH] LUDOC-222 mount: Fix some issue with mount documentation In 33.5: - Missing 'localflock' - Missing 'nomgs' - Missing (no)user_fid2path - Missing (no)acl, but left out because it's marked as deprecated In 37.15.3: - Added user_fid2path and nouser_fid2path entries were added - 'nosvc' 'nomgs' and 'exclude' are listed twice - The 'nomgs' was misspelled as 'nomsgs' Signed-off-by: Matt Ezell Change-Id: I0fdf197f5c5fd5c8c4c8f82e390cd8dd945bff2b Reviewed-on: http://review.whamcloud.com/9128 Tested-by: Jenkins Reviewed-by: Andreas Dilger --- SystemConfigurationUtilities.xml | 54 +++++++++++++++++++++++----------------- UserUtilities.xml | 28 +++++++++++++++++++-- 2 files changed, 57 insertions(+), 25 deletions(-) diff --git a/SystemConfigurationUtilities.xml b/SystemConfigurationUtilities.xml index da51d84..fc39f27 100644 --- a/SystemConfigurationUtilities.xml +++ b/SystemConfigurationUtilities.xml @@ -1952,63 +1952,71 @@ mount.lustre Disables Access Control List support. - - - - In addition to the standard mount options and backing disk type (e.g. ext3) options, Lustre understands the following server-specific options: - - - - - - Option + verbose - Description + Enable mount/umount console messages. - - - nosvc + noverbose - Starts the MGC (and MGS, if co-located) for a target service, not the actual service. + Disable mount/umount console messages. - nomsgs + user_fid2path - Starts only the MDT (with a co-located MGS), without starting the MGS. + Enable FID to path translation by regular users.
