Asmca has grayed out Volumes and ASM Cluster File Systems 11.2.0.3

I've got a two node cluster which is up and running with the latest 11.2.0.3 grid install on Oracle Linux 6.3
I need to get a shared storage location I can use for File I/O testing, ASM looks like the solution with an ASM Cluster File System.
When I run asmca I do not have the ability to create these volumes or file systems as they are Grayed out.
I found some instructions on how to get it to work, and they said to use acfsload to start up the required daemons:
[root@oracleA bin]# ./acfsload start -s
ACFS-9459: ADVM/ACFS is not supported on this OS version: '2.6.39-300.17.3.el6uek.x86_64'
I installed Patches: 13146560, 14596051 - Which I thought would fix the problem. Rebooted after successfully applying the patches, but asmca still shows them greyed out
and not supported on this OS error persists.
I see some posts online saying to edit osds_acfslib.pm and update it to allow for the supported ORACLE version
Right now it shows: ($release =~ /^oraclelinux-release/))) # Oracle Linux
under /etc it only has oracle-release - could that have something to do with it not passing the check?
uname -r
2.6.39-300.17.3.el6uek.x86_64
From what I can tell this kernal should support asm..
Any help in getting these shared storage asm disks setup would be very helpful, oracleasm creates them and sees them fine for databases. Thanks.

Turns out the Kernel version 2.6.39 does not have support for the ASM Drivers for the ACFS mounting.
I'm going to have to use Oracle Linux 6.2 (instead of Oracle Linux 6.3) and rebuild my RAC to get a supported version of the drivers -> Kernel version 2.6.32

ASM Cluster File System

Hi Xperts
I have a two nodes RAC and I need to create a Shared filesystem between the nodes, so I think in using ACFS, the problem is when I open ASMCA the ACFS tab is disable and I´m not able to start the ACFS driver. So I want to be sure that I won´t be able to use ACFS or if I am missing something.
I execute this:
[root@MPE66 bin]# ./acfsload start -s

Possible fix for no audio & grayed-out volume control

Hi, I just thought I'd post this fix I found for my Mac Mini losing audio and also having the volume control grayed-out as if permanently muted.
I have had this problem a couple of times on my Intel 2 GHz Core 2 Duo Mac Mini. I have tried some of the software solutions found on the web such as zapping PRAM, deleting certain Plists, etc. But in my experience the fix that has worked is to open the Mac Mini and unseat and then reseat the orange Foxconn ribbon audio cable where it connects from the Mini's audio board to what I assume is the main circuit board. Then when you reassemble and turn on your Mac, audio will be back.
My theory is that unplugging and re-plugging USB and audio cables on the back of the Mini near the audio board eventually loosens the internal ribbon cable and causes the audio to stop working. My latest attempt at a permanent solution is to have USB and analog 2.5mm stereo audio 'extender' cables plugged in on the back of my Mini, which loop forwards over the top of the Mini where they are all taped down securely. This allows me to plug and unplug cables without ever disturbing the actual USB and audio ports on the back of the Mini. I am hoping this will help avoid the lost audio & grayed-out volume control problem in the future since the connection of the internal audio ribbon cable is less likely to be disturbed. It is a somewhat ugly solution but seems to be working so far. I'll post later on if the volume control gets grayed out again even with these measures.

Not on mac though

Wifi of my iphone 4s has grayed out within 3 months of my purchase..I have now got a replacement from Apple

Wifi of my iphone 4s has grayed out within 3 months of my purchase..I have now got a replacement from Apple but unfortunately it worked for only 1 day and the wifi got grayed out again...I tried resetting all my settings but all in vain. How many times have i to replace my iphone..Has Apple not thought of solving the wifi issues from the core. I have heard many users are having this problem. Why hasn't Apple taken any step to improve and solve this issue. After buying such a high end product, this is what u get??? Most of the Apple users are now shifting to Samsung phones..I was a great fan of Apple and have been using all apple products but this has really disheartened me..Apple please wake up!!!

What can I do, iPad disabled/lockout and iTunes keeps asking for password, I cannot restore...iTunes grays out backup and restore but my iPad and iPod shows on Apple etc..???

Try and force iPad into Recovery Mode:
1. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release the Sleep/Wake and Home buttons.
2. Connect USB cable to computer, leave the other end alone
3. Press and hold the Home button down and connect the docking end of cable to iPad
4. Continue holding the Home button until you see the "Connect To iTune" screen
5. Release the Home button
6. Open iTune
7. You should see "iTunes has detected an iPad in recovery mode"
8. Use iTune to restore iPad
Note: You need to be patient and repeat the above many times to recover your iPad

Sun QFS cluster file system with Veritas Volume Manager

Hi,
Can someone confirm whether it is possible to create a Sun QFS cluster file system (for Oracle RAC datafiles) using a VxVM volume?
Or must we use Solaris Volume Manager with QFS?
Thinking of storing the static part of the Oracle RAC DB on VxVM raw devices, and the dynamic part on a QFS file system to avoid the overhead of constantly adding new raw devices when i want to create datafiles.
Thanks,
Steve

Steve,
No, shared QFS is only supported on Solaris Volume Manager. I've not heard of any plans to test it on VxVM.
Why not keep the static parts of the DB on raw SVM devices? Why keep them on raw devices at all?

RAC 10gr2 using ASM for RMAN a cluster file system or a Local directory

The environment is composed of a RAC with 2 nodes using ASM. I have to determine what design is better for Backup and Recovery with RMAN. The backups are going to be saved to disk only. The database is only transactional and small in size
I am not sure how to create a cluster file system or if it is better to use a local directory. What's the benefit of having a recovery catalog that is optional to the database?
I very much appreciate your advice and recommendation, Terry

Arf,
I am new to RAC. I analyzed Alejandro's script. He is main connection is to the first instance; then through sql*plus, he gets connected to the second instance. he exits the second instance and starts with RMAN backup to the database . Therefore the backup to the database is done from the first instance.
I do not see where he setenv again to change to the second instance to run RMAN to backup the second instance. It looks to me that the backup is only done to the first instance, but not to the second instance. I may be wrong, but I do not see the second instance backup.
Kindly, I request your assistance on the steps/connection to backup the second instance. Thank you so much!! Terry

Cluster file system and BDB - does it work ?

Hi,
I've read in the reference guide that:
" No commercial remote filesystem of which we're aware supports
coherent, distributed shared memory for remote-mounted files"
What about cluster file systems like veritas cluster file system ?
Can I use this file system with BDB ?
I'm trying to find a solution for having one database visible from two computers.
Reader and writer exist on each machine. Any clue how to do that ?
best regards
Moris

Why would anyone want to use ASM Clustered File system?

DB Version: 11gR2
OS : Solaris, AIX, HP-UX
I've read about the new feature ACFS.
http://www.oracle-base.com/articles/11g/ACFS_11gR2.php
But why would anyone want to store database binaries in a separate Filesystem created by Oracle?

Hi Vitamind,
how do these binaries interact with the CPU when they want something to be done?
ACFS should work with Local OS (Solaris) to communicate with the CPU . Isn't this kind of double work?ACFS dont work with .... but provide filesystem to Local S.O
There may be extra work, but that's because there are more resources that a common filesystem.
Oracle ACFS executes on operating system platforms as a native file system technology supporting native operating system file system application programming interfaces (APIs).
ACFS is a general purpose POSIX compliant cluster file system. Being POSIX compliant, all operating system utilities we use with ext3 and other file systems can also be used with Oracle ACFS given it belongs to the same family of related standards.
ACFS Driver Model
An Oracle ACFS file system is installed as a dynamically loadable vendor operating system (OS) file system driver and tool set that is developed for each supported operating system platform. The driver is implemented as a Virtual File System (VFS) and processes all file and directory operations directed to a specific file system.
It makes sense you use the ACFS if you use some of the features below:
• Oracle RAC / RAC ONE NODE
• Oracle ACFS Snapshots
• Oracle ASM Dynamic Volume Manager
• Cluster Filesystem for regular files
ACFS Use Cases
• Shared Oracle DB home
• Other “file system” data
• External tables, data loads, data extracts
• BFILES and other data customer chooses not to store in db
• Log files (consolidates access)
• Test environments
• Copy back a previous snapshot after testing
• Backups
• Snapshot file system for point-intime backups
• General purpose local or cluster file system
• Leverage ASM manageability
Note : Oracle ACFS file systems cannot be used for an Oracle base directory or an Oracle grid infrastructure home that contains the software for Oracle Clusterware, Oracle ASM, Oracle ACFS, and Oracle ADVM components.

Levi Pereira

IS RAW DEVICES SUPPORTED OVER A CLUSTER FILE SYSTEM

Can raw partions be defined for datafiles after having choosen Cluster file system as storage option for database while creating fresh database using
DBCA?

> Do update on how the partitions have to be defined in either cases?
For both ASM and OCFS, a partition must exist on the disk - it can be of any partition type. Does not matter. Simply that the s/w references a partition and not an entire disk.
So for example, /dev/sdaf and dev/sdag are two shared devices on the cluster (LUNs on the SAN or whatever).
You create a partition on each. E.g
# fdisk -l /dev/sdaf
Disk /dev/sdaf: 36.5 GB, 36573020160 bytes
255 heads, 63 sectors/track, 4446 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdaf1 1 4446 35712463+ 83 LinuxTo use the first device as a OCFS device, you need to build an ocfs file system on it using mkfs.
And then it can be mounted as a "normal" cooked file system mount. Remember that /etc/fstab needs to be updated for mounting it on startup.
To use the second device for ASM, you have two choices. If you have the ASMlib kernel module installed, you can use that to configure a volume label and assign it for use by ASM.
Alternatively, you simply map the device (partition) to a raw device for detection by ASM. E.g.
# raw /dev/raw/raw1 /dev/sdag1Of course, you also need to make this permanent by updating the raw device list config file so that this mapping is performed on reboot. On Linux, this is the /etc/sysconfig/rawdevices file. Also remember that the user and group access for the logical raw device created, must allow ASM full access to it (e.g. use chmod oracle.dba /dev/raw/raw1).
In a nutshell, this is how to raw devices are used as ocfs and asm volumes. (on RHEL specifically, but I expect no major differences in this approach on other o/s's)

Crashes and read-only file systems

Notice: I apolgize for the long post, I've tried to be as thorough as possible. I have searched everywhere for possible solutions, but things I've found end up being temporary workarounds or don't apply to my situation. Any help, even as simple as, "have you checked out XYZ log, it's hidden here", would be greatly appreciated. Thanks
I'm not sure what exactly caused the issues below, but they did start to happen within a day of running pacman -Syu. I hadn't run that since I first installed Arch on December 2nd of this year.
Setup:
Thinkpad 2436CTO
UEFI/GPT
SSD drive
Partitions: UEFISYS, Boot, LVM
The LVM is encrypted and is broken up as: /root, /var, /usr, /tmp, /home
All LVM file systems are EXT4 (used to have /var and /tmp as ReiserFS)
The first sign that something was wrong was gnome freezing. Gnome would then crash and I'd get booted back to the shell with all filesystems mounted as read-only. I started having the same issues as this OP:
https://bbs.archlinux.org/viewtopic.php?id=150704
At the time, I had /var and /tmp as ReiserFS, and would also get reiserfs_read_locked_inode errors.
When shutting down (even during non-crashed sessions) I would notice this during shutdown:
Failed unmounting /var
Failed unmounting /usr
Followed by a ton of these:
device-mapper: remove ioctl on <my LVM group> failed: Device or resource busy
Nother of these errors had ever appeared before.
After hours of looking for solutions (and not finding any that worked) I was convinced (without any proof) that my Reiser file systems were corrupt and so I reformatted my entire SSD and started anew - not the Arch way, I know I set all logical volumes as EXT4.
After started anew, I noticed
device-mapper: remove ioctl on LVM_SysGroup failed: Device or resource busy
was still showing up, even with just a stock Arch setup (maybe even when powering off via Arch install ISO, don't remember). After a lot of searching, I found that most people judged it a harmless error, so I ignored it and continued setting up Arch.
I set up Gnome and a basic LAMP server, and everything seemed to work for a couple of hours. Soon after, I got the same old issues back. The System-journald issue came back and per the workaround on https://bbs.archlinux.org/viewtopic.php?id=150704 and a couple other places, I rotated the journals and stopped journald from saving to storage. That seemed to stop THOSE errors from at least overwhelming the shell, but I would still get screen freezes, crashes, and read-only file systems.
I had to force the laptop to power off, since poweroff/reboot/halt commands weren't working (would get errors regarding the filesystems mounted as read-only).
I utilized all disk checking functions possible. From running the tests (SMART test included) that came as part of my laptop's BIOS to full blown fsck. All tests showed the drive was working fine, and Fsck would show everything was either clean, or
Clearing orphaned inode ## (uid=89, gid=89, mode=0100600, size=###
Free blocks count wrong (###, counted=###)
Which I would opt to fix. Nothing serious, though.
I could safely boot back into Arch and use the system fine until the system decides to freeze/crash and do the above all over again.
The sure way of recreating this for me is to run a cron job on a local site I'm developing. After a brief screen freeze (mouse still moveable but everything is otherwise unreponsive) I'll systemctl status mysqld.service and notice that mysqld went down.
It seems that it's at this point my file systems are mounted as read only, as trying to do virtually anything results in:
unable to open /var/db/sudo/...: Read-only file system
After some time, X/Gnome crashes and I get sent back to shell with
ERROR: file_stream_metrics.cc(37)
RecordFileError() err = 30 source = 1 record = 0
Server terminated successfully (0)
Closing log file.or_delegate.h(30)] sqlite erro1, errno 0: SQL logic error or missing database[1157:1179
rm: cannot remove '/tmp/serverauth.teuroEBhtl': Read-only file system
Before all this happened, I was using Arch just fine for a few weeks. I wiped the drives and started anew, and this still happens with just the minimal number of packages installed.
I've searched for solutions to each individual problem, but come across a hack that doesn't solve anything (like turning off storing logs for journal), or the solution doesn't apply to my case.
At this point, I'm so overwhelmed I'm not even sure where exactly to pick up figuring this issue out.
Thanks in advance for any help

Did this occur when you booted from the live/install media?
What is your current set up? That is, partitions, filesystems etc. I take it you have not yet reinstalled X but are in the default CLI following installation?
If turning off log storage didn't help, reenable it so that you may at least stand a chance of finding something useful.
What services, if any, are you running? What non-default daemons etc.?
Does it happen if you keep the machine off line?
Have you done pacman -Syu since installation and dealt with any *.pacnew files?

Linux Cluster File System partitions for 10g RAC

Hi Friends,
I planned to install 2 Node Oracle 10g RAC on RHEL and I planned to use Linux File system itself for OCR,Voting Disk and datafiles (no OCFS2/RAW/ASM)
I am having SAN storage.
I would like to know how do i create shared/cluster partitions for OCR,Voting Disk and Datafiles (common storage on SAN).
Do i need to install any Linux cluster file system for creating these shared partitions (as we have sun cluster in solaris)?
If so let me know what versions are supported and provide the necessary Note / Link
Regards,
DB

ASM Vs File system

1. With file system, we were able to set some threshold alerts at the OS mount point level. Is this possible with ASM since it is a raw device at the OS level?
2. The ASM directories are logical and is visible ONLY at the oracle ASM level. True?
3. Is cold backup an option with ASM?
4. Is RMAN the only solution with ASM disks?
5. Are there any suggested Hardware snap/clone available for ASM storage?
Thanks for your insight on this.

5. Are there any suggested Hardware snap/clone available for ASM storage?1. Not possible from an OS point-of-view. See earlier reply for workaround;
2. Yep, or use asmcmd (from the ASM ORACLE_HOME) or ftp
3. If you use RMAN to cold-backup: yes. You cannot use a regular backup to back up your devices, unless you have designated files as 'disks' to ASM (But who would want that?). In this case you should shut down ASM and backup the file system where these files reside.
4. Yes, it is.
5. That depends on your hardware configuration. It is possible to run ASM on concurrent/shared, host based mirrored volume groups/volumes. If you use SAN technology, you can always verify whether these options are available from the storage manufacturer. However, I would be really careful with these, always taking things down before taking snapshots/flashcopies/clones/whatever you call them.
HTH.
