Which file defines mount point

In Linux, /etc/fstab tells the OS the details of a volume when mounting it. I wanted to edit this to have certain devices use different mount points than they do automatically, so either I'm not doing it properly or OS X works a little differently in this respect.
Thanks.
p.s. I have Tiger, I just haven't updated my info (below)

Brad,
See if this info helps you.

ASM vs ext3 File system(mount point)

Please suggest which one is better for small databases.
ASM or ext3 File system(mount point)?
Any metalink note.

ASM better if you do not want to play with I/O tiuning, (if you tune ext3 file system it woud be the same from performace view),
but it more compilcated for admininstering database files in ASM then in ordinary file system.
Oracle is recomending to use ASM for database file system.
I woud think if you have some development database and nead a lot of cloning, moving of datafiles its better to use ordinary file system,
so you can use copy OS comands, not so complicated.
If you nead some striping, miroring, snapshoting from ext3 you can use LVM on unix/linux.
I am not sure but I think what striping or miroring is better on ASM then on LVM, becouse ASM is doing it better for databse I/O.

New zone and inherited file system mount point error

Hi - would anyone be able to help with the following error please. I've tried to create a new zone that has the following inherited file system:
inherit-pkg-dir:
dir: /usr/local/var/lib/sudo
But when I try to install it fails with:
root@tdukunxtest03:~ 532$ zoneadm -z tdukwbprepz01 install
A ZFS file system has been created for this zone.
Preparing to install zone <tdukwbprepz01>.
ERROR: cannot create zone <tdukwbprepz01> inherited file system mount point </export/zones/tdukwbprepz01/root/usr/local/var/lib>
ERROR: cannot setup zone <tdukwbprepz01> inherited and configured file systems
ERROR: cannot setup zone <tdukwbprepz01> file systems inherited and configured from the global zone
ERROR: cannot create zone boot environment <tdukwbprepz01>
I've added this because unknown to me when I installed sudo from sunfreeware in the global it requires access to /usr/local/var/lib/sudo - sudo itself installs in /usr/local. And when I try to run any sudo commands in the new zone it gave this:
sudo ls
Password:
sudo: Can't open /usr/local/var/lib/sudo/tdgrunj/8: Read-only file system
Thanks - Julian.

Think I've just found the answer to my problem, I'd already inherited /usr ..... and as sudo from freeware installs in /usr/local I guess this is never going to work. I can only think to try the sudo version of the Solaris companion DVD or whatever it's called.

Time Machine (OSX) doesn't back up files in Mount Point or Disk Image File

Hi all,
I have two disk images which are scripted to be mounted on login. These two disk images are always mounted to the same location. These two disk images are encrypted TrueCrypt volumes.
Time Machine (TM) will only back up the disk images the first time they are mounted, but not after that. As I modify documents within the volumes throughout the day, the modified timestamps are adjusted properly. However, TM does not back them up. TM never backs up the mount points which are two folders within my home directory.
Any ideas as to why neither the mount point or the image files are backed up? Do the image files have to be closed (unmounted) after being modified for TM to back them up?
Now if TM won't back up the image files because they are locked/open, then why does it back them up the first time even though they are mounted? Also, from what I've read, TM should back up any HFS+ drive which is mounted. Both these drives are HFS+, so it should back up the mount points? I can verify this by doing a 'mount' in the terminal, the following is echo'd back:
/dev/disk0s2 on / (hfs, local, journaled) (Main System Drive)
/dev/disk1 on /Users/username/Folder1 (hfs, local, nodev, nosuid, journaled, noowners, mounted by username) (First TrueCrypt volume)
/dev/disk2 on /Users/username/Folder2 (hfs, local, nodev, nosuid, journaled, noowners, mounted by username)(Second TrueCrypt volume)
Any ideas will help!
Thanks,
Chris

Here is the resolution:
Apparently time machine checks the parent folder's timestamp before moving into that folder to look for modified files.
So as I was modifying files, the timestamps on the volumes were changing but not the containing directory. Because of this, TimeMachine saw the parent directory had not changed, so did not look for the changed volumes inside.
So to resolve this, I wrote a simple touch script which touches the parent directory to match the modified volumes timestamp (if there is a modified volume).
Thanks,
Chris

ZFS mount points and zones

folks,
a little history, we've been running cluster 3.2.x with failover zones (using the containers data service) where the zoneroot is installed on a failover zpool (using HAStoragePlus). it's worked ok but could be better with the real problems surrounding lack of agents that work in this config (we're mostly an oracle shop). we've been using the joost manifests inside the zones which are ok and have worked but we wouldn't mind giving the oracle data services a go - and the more than a little painful patching processes in the current setup...
we're started to look at failover applications amongst zones on the nodes, so we'd have something like node1:zone and node2:zone as potentials and the apps failing between them on 'node' failure and switchover. this way we'd actually be able to use the agents for oracle (DB, AS and EBS).
with the current cluster we create various ZFS volumes within the pool (such as oradata) and through the zone boot resource have it mounted where we want inside the zone (in this case $ORACLE_BASE/oradata) with the global zone having the mount point of /export/zfs/<instance>/oradata.
is there a way of achieving something like this with failover apps inside static zones? i know we can set the volume mountpoint to be what we want but we rather like having the various oracle zones all having a similar install (/app/oracle etc).
we haven't looked at zone clusters at this stage if for no other reason than time....
or is there a better way?
thanks muchly,
nelson

i must be missing something...any ideas what and where?

Logical Disk (Mount Point) Performance Counters

We're currently running SCOM 2012 SP1, Management Servers and Agents are all at UR8
The Windows Server Operating system management pack is at 6.0.7292.0
We're successfully collecting performance metrics which are not mount points but the performance metrics for mount points are missing. We've enabled the discovery for mount points.
The error that I'm seeing on the agent machines is:
In PerfDataSource, could not resolve counter instance LogicalDisk, Avg. Disk Write Queue Length, G:\Archive\. Module will not be unloaded.
One or more workflows were affected by this.
Workflow name: Microsoft.Windows.Server.2008.LogicalDisk.AverageDiskWriteQueueLength.Collection
Instance name: G:\Archive\
Instance ID: {EE651C3D-A5B8-E5C2-459E-8B6C27F8B813}
We used to be able to collect this performance data but now it's failing. Does anyone know how to resolve this?

Hi!
There was a new MP version fixing Mount Point monitoring online earlier this year but it has been pulled since there where some bugs.
Expect the new version available within the next couple of weeks. I assume your issue will be fixed there.
Cheers,

Live upgrade, zones and separate mount points

Hi,
We have a quite large zone environment based on Solaris zones located on VxVM/VxFS. I know this is a doubtful configuration but the choice was made before i got here and now we need to upgrade the environment. Veritas guides says its fine to locate zones on Veritas, but i am not sure Sun would approve.
Anyway, sine all zones are located on a separate volume i want to create a new one for every zonepath, something like:
lucreate -n upgrade -m /:/dev/dsk/c2t1d0s0:ufs -m /zones/zone01:/dev/vx/dsk/zone01/zone01_root02:ufs
This works fine for a while after integration of 6620317 in 121430-23, but when the new environment is to be activated i get errors, see below[1]. If i look at the command executed by lucreate i see that the global root is mounted, but by zoneroot does not seem to have been mounted before the call to zoneadmd[2]. While this might not be a supported configuration, VxVM seems to be supported and i think that there are a few people out there with zonepaths on separate disks. Live upgrade probably has no issues with the files moved from the VxFS filesystem, that parts has been done, but the new filesystems does not seem to get mounted correctly.
Anyone tried something similar or has any idea on how to solve this?
The system is a s10s_u4 with kernel 127111-10 and Live upgrade patches 121430-25, 121428-10.

I updated my manual pages got a reminder of the zonename field for the -m option of lucreate. But i still have no success, if i have the root filesystem for the zone in vfstab it tries to mount it the current root into the alternate BE:

Mobile accounts WHICH MOUNT POINT?

How does a machine handling a mobile account
a. know how to set $HOME ?
b. know where to mount the folder during sync?
The scenario and problem:
(can u help?)(you'll win a free beer if you come to Switzerland).
I have the user's files stored in /Volumes/team1/users/user1
The folder /Volumes/team1 is mounted on a local drive on server1.
The server1 share point, called 'users' is /Volumes/team1/users
(sounds simple.. doesn't it
In config-scenario1 I do this:
The user's share point URL is afp://server1.disneyland.ch/users
The path to home folder is user1
The full path is /Network/Servers/server1.disneyland.ch/users/user1
THIS WORKS ON CLIENT MAC1
When logged in (via login panel), the $HOME is set to /Users/user1
and during syncing I see /Volumes/users mounted temporarily (weird,.. it used to show the temporary mount as /Network/Servers/server1.disneyland.ch/users )
user1@mac1:~ > pwd
/Users/user1
user1@mac1:~ >
THIS WORKS ON SERVER1
When I ssh into the user, on server1,
I see $HOME set to /Network/Servers/server1.disneyland.ch/users/user1
user1@server1:~ > pwd
/Network/Servers/server1.disneyland.ch/users/user1
user1@server1:~ >
THIS DOES NOT WORK ON SERVER2
On server2 where the same external drive is mounted (it's an Xsan using fiber-channel)
I get this:
user1$ cd ~
-bash: cd: /Network/Servers/server1.disneyland.ch/users/user1: No such file or directory
SOLUTION1 (that fails)(aka config-scenario 2)
The user's share point URL is afp://server1.disneyland.ch/users
The path to home folder is user1
Set the full path to /Volumes/team1/users/user1
THIS WORKS ON MAC1
THIS WORKS ON SERVER1
THIS CAUSES PROBLEMS ON SERVER2 : (see this posting: http://forums.macosxhints.com/showthread.php?p=581557 ).
Questions :
1. How is the HOME folder determined by the computer? Despite the two config-scenarios, the client mac1 uses HOME as /Users/user1 (as it should) but not on Server1 or Server2 (on Server1 it always uses the value in the full path specified in the Mobility>Home for the user)(In Server2 it sometimes uses that value and sometimes it uses the previous configuration value).
2. How is the MOUNT on the client determined? It seems that it is always /Volumes/users (as it should?); Perhaps it is identified by the system seeing what is behind the user's share point? What's weird is that I'm sure/certain that at one point, under config-scenario1, the mount point on mac8 was NOT /Volumes/users but rather /Network/Servers/server1.disneyland.ch ! Did I dream that ?
3. How can I PREVENT the mount happening on Server2 (it's mounting on top of the existing /Volumes/team1/users !!) ?
4. If I DO accept config-scenario1, couldn't I just create a symbolic link on server2 in /Network/Server/server1.disneyland.ch/users-->/Volumes/team1/users ?? Actually this doesn't work because even with sudo I can't mkdir /Networks/Servers/server1.disneyland.ch into which I wold have make the users-> link
ARGHHH!
Thanx for any insight.

Hi Marco_Ben_IT,
Do not install SQL Server to the root directory of a mount point, setup fails when the root of a mounted volume is chosen for the data file directory, we must always specify
a subdirectory for all files. This has to do with how permissions are granted. If you must put files in the root of the mount point you must manually manage the ACLs/permissions. We need to create a subfolder under the root of the mount point, and install
there.

Nfs mount point does not allow file creations via java.io.File

Folks,
I have mounted an nfs drive to iFS on a Solaris server:
mount -F nfs nfs://server:port/ifsfolder /unixfolder
I can mkdir and touch files no problem. They appear in iFS as I'd expect. However if I write to the nfs mount via a JVM using java.io.File encounter the following problems:
Only directories are created ? unless I include the user that started the JVM in the oinstall unix group with the oracle user because it's the oracle user that writes to iFS not the user that creating the files!
I'm trying to create several files in a single directory via java.io.File BUT only the first file is created. I've tried putting waits in the code to see if it a timing issue but this doesn't appear to be. Writing via java.io.File to either a native directory of a native nfs mountpoint works OK. ie. Junit test against native file system works but not against an iFS mount point. Curiously the same unit tests running on PC with a windows driving mapping to iFS work OK !! so why not via a unix NFS mapping ?
many thanks in advance.

Hi Diep,
have done as requested via Oracle TAR #3308936.995. As it happens the problem is resolved. The resolution has been not to create the file via java.io.File.createNewFile(); before adding content via an outputStream. if the File creation is left until the content is added as shown below the problem is resolved.
Another quick question is link creation via 'ln -fs' and 'ln -f' supported against and nfs mount point to iFS ? (at Operating System level, rather than adding a folder path relationship via the Java API).
many thanks in advance.

Btrfs with different file systems for different mount points?

Hey,
I finally bought a SSD, and I want to format it to f2fs (and fat to boot on UEFI) and install Arch on it, and in my old HDD I intend to have /home and /var and try btrfs on them, but I saw in Arch wiki that btrfs "Cannot use different file systems for different mount points.", it means I cannot have a / in f2fs and a /home in btrfs? What can I do? Better use XFS, ZFS or ext4 (I want the faster one)?
Thanks in advance and sorry my english.

Just a few weeks ago many of us were worrying about massive data loss due to a bug introduced in kernel 3.17 that caused corruption when using snapshots. Because btrfs is under heavy developement, this sort of thing can be expected. That said, I have my entire system running with btrfs. I have 4 volumes, two raid1, a raid0 and a jbod. I also run rsync to an ext4 partition and ntfs. Furthermore I make offline backups as well.
If you use btrfs make sure you have backups and make sure you are ready to use them. Also, make sure you check sum your backups. rsync has the option to use checksums in place of access times to determine what to sync.

How can we find out the disk which is used for a mount point

How can we find out the disk which is used for a mount point?
one of our mount point(/u03/oracle/prod) was using high I/O and this was causing slowness in the server.
I can see a disk operation error in errpt at the same time as below. Wanted to check whether the mount point /u03/oracle/prod is using the disk hdisk31
$errpt|more
IDENTIFIER TIMESTAMP T C RESOURCE_NAME DESCRIPTION
DXB78877 1125032114 T H hdisk31 DISK OPERATION ERROR
OS version:AIX 6.1
DB:11.2.0.2

this is the output for cat /etc/filesystem
/u02:
        dev             = /dev/fslv00
        vfs             = jfs2
        log             = /dev/loglv00
        mount           = true
        options         = rw
        account         = false
/u01:
        dev             = /dev/fslv01
        vfs             = jfs2
        log             = /dev/loglv00
        mount           = true
        options         = rw
        account         = false

Which file defines mount point
