* config: allow Array line to contain array name without /dev/md/ prefix.NeilBrown2009-05-111-1/+7
| | | | | | | | | | | | | | | For consistency with --create and --assemble, allow the array name given in mdadm.conf to exclude the "/dev/md/" prefix. So e.g. ARRAY home uuid=whatever is treated like ARRAY /dev/md/home uuid=whatever Also exclude names which create_mddev will reject. Signed-off-by: NeilBrown <neilb@suse.de>
* config: support "ARRAY <ignore> ..." lines in mdadm.confNeilBrown2009-05-111-0/+2
| | | | | | | | | | | | | | Sometimes we want to ensure particular arrays are never assembled automatically. This might include an array made of devices that are shared between hosts. To support this, allow ARRAY lines in mdadm.conf to use the word "ignore" rather than a device name. Arrays which match such lines are never automatically assembled (though they can still be assembled by explicitly giving identification information on the mdadm command line.

* Wait for POLLPRI on /proc or /sys files.NeilBrown2009-04-141-1/+1
| | | | | | | | | | | | | From 2.6.30, /proc/mounts and various /sys files will probably always returns 'readable' to select, so we will need to wait on POLLPRI to get the 'new data is available' signal. When using select, this corresponds to an 'exception', so adjust calls to select accordingly. In one case we sometimes wait on a socket and sometime on /proc/mounts, so we need to test which.

| * Monitor: send --test message for arrays in /proc/mdstat that aren't in ↵NeilBrown2009-02-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | mdadm.conf "mdadm --monitor --test --scan" currently only sends test messages for arrays listed on the command line or in /etc/mdadm.conf. With this patch it also reports on any active arrays, which is more in line with the description in the manpage. Thanks to Andrew Walrond <andrew@walrond.org> for reporting this error.

| | | | | | | | | | | | | | | | | | | | i.e. in mdadm.conf you can have a line like ARRAY uuid=whatever and it will use auto-name-generation to give a name to the array at assemble-time. The is different from blind auto-assembly in that the array will be treated as 'local'.

| | | | | | | | | | | | | | | | | | Root file systems backed by external metadata arrays need to be explicitly checkpointed near the time the rootfs is marked readonly as userspace will not have an opportunity to react to the final shutdown of the array.

* | --wait-clean: shorten timeoutDan Williams2008-10-151-12/+23
| | | | | | | | | | | | | | | | | | | | | | | | Set the safemode timeout to a small value to get the array marked clean as soon as possible. We don't write 'clean' directly as it may cause mdmon to miss a 'write-pending' event. Include a couple fixes to sysfs_set_safemode(): 1/ 0 pad the milliseconds field 2/ workaround input truncation in the kernel Signed-off-by: Dan Williams <dan.j.williams@intel.com>

| | | | | | | | | | | | | | | | | | For use in distro shutdown scripts with a RAID root file system. Returns immediately if the array is 'readonly', or not an externally managed array. It is up to the distro's scripts to make sure no new writes hit the device after this returns 'true'. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The action we are waiting for may not be complete until the monitor has had a chance to take action on the result. The following script can now remove the device on the first attempt, versus a few attempts with the original Wait(): #!/bin/bash #export MDADM_NO_MDMON=1 export IMSM_DEVNAME_AS_SERIAL=1 ./mdadm -Ss ./mdadm --zero-superblock /dev/loop[0-3] echo 2 > /proc/sys/dev/raid/speed_limit_max ./mdadm --create /dev/imsm /dev/loop[0-3] -n 4 -e imsm -a md ./mdadm --create /dev/md/r1 /dev/loop[0-3] -n 4 -l 5 --force -a mdp ./mdadm --fail /dev/md/r1 /dev/loop3 ./mdadm --wait /dev/md/r1 x=0 while ! ./mdadm --remove /dev/imsm /dev/loop3 > /dev/null 2>&1 do x=$((x+1)) done echo "removed after $x attempts" ./mdadm --add /dev/imsm /dev/loop3 Include 2 small cleanups: * remove the almost open coded fd2devnum() in Wait() by introducing a new utility routine stat2devnum() * teach connect_monitor() to parse the container device from a subarray string Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* Fix for segfault when reading /proc/mdstatNeil Brown2008-04-281-0/+1
| | | | | | | | | Some kernel versions don't put a space between 'active' and '(auto-read-only)' in /proc/mdstat. This causes a parsing problem leaving 'level' set to NULL which causes a crash. So synthesise a space there if it is missing, and check for 'level' to be NULL and don't de-ref if it is.

* Enhance raid4 support: --assemble and --monitor wasn't quite happy with it.Doug Ledford2007-07-091-5/+6
| | | | | | | | | | | | | | | | | | | | | | | From: Doug Ledford <dledford@redhat.com> This one actually does a couple things. Mainly related to raid4, but kinda touches other raid levels some. When creating a raid4 array, treat it like a raid5 array in that we create it in degraded mode by default and add the last disk as a spare. Besides speeding things up, this has a second effect that it makes mdadm more consistent. In order to create a degraded raid5 array, you need only passing missing as one of the devices. For a degraded raid4 array, prior to this patch, you must pass assume-clean or else it refuses to create the array. Even force won't make it work without assume-clean. With the patch, raid4 behaves identical to raid5. Separate from that, the monitor functionality completely ignores raid4 arrays. That seems to stem from the code that checks to see if the array is part of a long list of types. It seems easier to check which array types *aren't* redundant instead of listing the ones that are redundant and missing some of them. This makes the monitor service actually watch raid4 arrays.
* Mark some files FD_CLOEXEC to protect sendmail from them.Doug Ledford2007-07-091-0/+1
| | | | | | | | | | | From: Doug Ledford <dledford@redhat.com> When running with SELinux enabled and using mdadm to monitor devices, attempts to send emails to an admin will be blocked because mdadm is holding open /proc/mdstat without setting the FD_CLOEXEC flag. As a result, sendmail has an open descriptor to /proc/mdstat after the popen() call, which SELinux decides isn't really any of sendmail's business and so sendmail gets denied.

| | | | | | | | | | | | From: Luca Berra <bluca@vodka.it> glibc 2.4 is pedantic on ignoring return values from fprintf, fwrite and write, so now we check the rval and actually do something with it. in the Grow.c case i only print a warning, since i don't think we can do anything in case we fail invalidating those superblocks (is should never happen, but then...)
