From ae084046cce12a1ce707b5d141f092b4c011e1b3 Mon Sep 17 00:00:00 2001 From: Amar Tumballi Date: Wed, 19 Jul 2017 23:08:05 +0530 Subject: glusterfsd: allow subdir mount Changes: 1. Take subdir mount option in client (mount.gluster / glusterfsd) 2. Pass the subdir mount to server-handshake (from client-handshake) 3. Handle subdir-mount dir's lookup in server-first-lookup and handle all fops resolution accordingly with proper gfid of subdir 4. Change the auth/addr module to handle the multiple subdir entries in option, and valid parsing. How to use the feature: `# mount -t glusterfs $hostname:/$volname/$subdir /$mount_point` Or `# mount -t glusterfs $hostname:/$volname -osubdir_mount=$subdir /$mount_point` Option can be set like: `# gluster volume set auth.allow "/subdir1(192.168.1.*),/(192.168.10.*),/subdir2(192.168.8.*)"` Updates #175 > Reviewed-At: https://review.gluster.org/17141/ Change-Id: I7ea57f76ddbe6c3862cfe02e13f89e8a39719e11 Signed-off-by: Amar Tumballi Reviewed-on: https://review.gluster.org/17968 Smoke: Gluster Build System CentOS-regression: Gluster Build System Reviewed-by: Shyamsundar Ranganathan --- doc/glusterfs.8 | 3 + doc/mount.glusterfs.8 | 7 +- glusterfsd/src/glusterfsd.c | 10 ++ glusterfsd/src/glusterfsd.h | 1 + libglusterfs/src/client_t.c | 16 +- libglusterfs/src/client_t.h | 8 +- libglusterfs/src/glusterfs.h | 3 + libglusterfs/src/options.c | 62 ++++++- tests/bugs/quota/bug-1292020.t | 9 +- tests/features/subdir-mount.t | 99 +++++++++++ xlators/mount/fuse/utils/mount.glusterfs.in | 17 +- xlators/protocol/auth/addr/src/addr.c | 227 ++++++++++++++++--------- xlators/protocol/client/src/client-handshake.c | 21 ++- xlators/protocol/server/src/server-common.c | 68 ++++++-- xlators/protocol/server/src/server-common.h | 6 +- xlators/protocol/server/src/server-handshake.c | 180 ++++++++++++++------ xlators/protocol/server/src/server-helpers.c | 10 +- xlators/protocol/server/src/server-rpc-fops.c | 107 +++++++----- xlators/protocol/server/src/server.c | 1 + xlators/protocol/server/src/server.h | 3 + 20 files changed, 659 insertions(+), 199 deletions(-) create mode 100644 tests/features/subdir-mount.t diff --git a/doc/glusterfs.8 b/doc/glusterfs.8 index 701c25ecfac..520150a55e9 100644 --- a/doc/glusterfs.8 +++ b/doc/glusterfs.8 @@ -101,6 +101,9 @@ Mount the filesystem in 'worm' mode. .TP \fB\-\-xlator\-option=VOLUME\-NAME.OPTION=VALUE\fR Add/Override a translator option for a volume with the specified value. +.TP +\fB\-\-subdir\-mount=SUBDIR\-MOUNT\-PATH\fR +Mount subdirectory instead of the '/' of volume. .SS "Fuse options" .PP diff --git a/doc/mount.glusterfs.8 b/doc/mount.glusterfs.8 index 4e82c2fd57d..e16bbecb8b0 100644 --- a/doc/mount.glusterfs.8 +++ b/doc/mount.glusterfs.8 @@ -12,11 +12,11 @@ .SH NAME .B mount.glusterfs - script to mount native GlusterFS volume .SH SYNOPSIS -.B mount -t glusterfs [-o ] :/ +.B mount -t glusterfs [-o ] :/[/] .B .TP .B mount -t glusterfs [-o ] ,, -.B ,..:/ +.B ,..:/[/] .TP .TP .B mount -t glusterfs [-o ] @@ -95,6 +95,9 @@ Disable direct I/O mode in fuse kernel module \fBcongestion\-threshold=\fRN Set fuse module's congestion threshold to N [default: 48] .TP +\fsubdir\-mount=\fRN +Set the subdirectory mount option [default: NULL, ie, no subdirectory mount] +.TP .TP \fBbackup\-volfile\-servers=\fRSERVERLIST Provide list of backup volfile servers in the following format [default: None] diff --git a/glusterfsd/src/glusterfsd.c b/glusterfsd/src/glusterfsd.c index ebf58706107..78b06bf4701 100644 --- a/glusterfsd/src/glusterfsd.c +++ b/glusterfsd/src/glusterfsd.c @@ -160,6 +160,8 @@ static struct argp_option gf_options[] = { "Enable SELinux label (extended attributes) support on inodes"}, {"capability", ARGP_CAPABILITY_KEY, 0, 0, "Enable Capability (extended attributes) support on inodes"}, + {"subdir-mount", ARGP_SUBDIR_MOUNT_KEY, "SUBDIR-PATH", 0, + "Mount subdirectory given [default: NULL]"}, {"print-netgroups", ARGP_PRINT_NETGROUPS, "NETGROUP-FILE", 0, "Validate the netgroups file and print it out"}, @@ -1277,6 +1279,14 @@ no_oom_api: case ARGP_LOCALTIME_LOGGING_KEY: cmd_args->localtime_logging = 1;
