File system mount prob

after starting my server i found some of the partitions( where oracle data files are located) not mounted.what soud i do to mount properly that file system

Hi,
Are you using Linux? You need to add the for these files systems to /etc/fstab. Suppose you have a hard disk /dev/sdc1 which is mounted on /u01 file system, add following line at the bottom of your /etc/fstab file (suppose you are using ext3 file system
/dev/sdc1 ext3 defaults 1 2This will auto mount your file system on every startup

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.

ZFS file system mount in solaris 11

Create a ZFS file system for the package repository in the root pool:
# zfs create rpool/export/repoSolaris11
# zfs list
The atime property controls whether the access time for files is updated when the files are read.
Turning this property off avoids producing write traffic when reading files.
# zfs set atime=off rpool/export/repoSolaris11
Create the required pkg repository infrastructure so that you can copy the repository
# pkgrepo create /export/repoSolaris11
# cat sol-11-1111-repo-full.iso-a sol-11-1111-repo-full.iso-b > \
sol-11-1111-repo-full.iso
# mount -F hsfs /export/repoSolaris11/sol-11-1111-repo-full.iso /mnt
# ls /mnt
# df -k /mnt
Using the tar command as shown in the following example can be a faster way to move the
repository from the mounted file system to the repository ZFS file system.
# cd /mnt/repo; tar cf - . | (cd /export/repoSolaris11; tar xfp -)
# cd /export/repoSolaris11
# ls /export/repoSolaris11
pkg5.repository README
publisher sol-11-1111-repo-full.iso
# df -k /export/repoSolaris11
# umount /mnt
# pkgrepo -s /export/repoSolaris11 refresh
=============================================
# zfs create -o mountpoint=/export/repoSolaris11 rpool/repoSolaris11
==============================================I am trying to reconfigure the package repository with above steps. when reached the below step
# zfs create -o mountpoint=/export/repoSolaris11 rpool/repoSolaris11
created the mount point but not mounted giving the error message
cannot mount ,directory not empty When restarted the box, threw service adm screen with error message
not able to mount all pointsPlease advise and Thanks in advance.

Hi.
Don't mix content of directory as mountpoint and what you see after FS was mounted.
On othet ZFS - mount point also clear. You see contetn of ZFS file system.
For check you can unmount any other ZFS and see that mountpoint also clear.
Regards.

UFS file system mount options

I'm doing some performance tuning on a database server. In mounting a particular UFS file system, I need to enable the "forcedirectio" option. However, the "logging" option is already specified. Is there any problem mounting this file system with BOTH "logging" and "forcedirectio" at the same time? I can do it and the system boots just fine but I'm not sure if it's a good idea or not. Anybody know?

Direct IO bypasses the page cache. Hence the name "direct".
Thus, for large-block streaming operations that do not access the same data more than once, direct IO will improve performance while reducing memory usage - often significantly.
IO operations that access data that could otherwise be cached can go MUCH slower with direct IO, especially small ones.

How to Stop Finder WEBDAVFS from requesting .hidden, ._Directory , ._FileName files after Remotes File System Mount has happened?

Hi,
After I have mounted remote directory on Finder , Finder requests for all file types including .hidden, ._Directory , ._FileName files and all such files which is creating havoc to the performance of the Finder.
Case 1 : In one Directory I have 500 files+directories. When the Finder tries to fetch the directory content it is sending requests for even .hidden, ._Directory , ._FileName files and so the request count grows exponentially causing breakdown for Finder. Its taking 10 mins to load the directory. The same directory request when posted by Transmit by Panic it loads within 30 secs. Transmit do not send request for ._* files/directory.
I am rejecting request for all hidden file request but they keep on coming in thousands.
Case 2 : Finder tries to refresh the file listing whenever the Finder window is brought to Focus.
Any help is appreciated. When I try to use find for such files to delete I see no listing!

/globaldevices on different file system mounts

IHAC that has a SC3.2 on a pair of V890's Solaris9-U5 and Veritas Foundation Suite 5 for boot disks.
I have noticed that the paths to /globaldevices are different:
/dev/vx/dsk/bootdg/rootdg_16vol 487863 5037 434040 2% /global/.devices/node@1
/dev/vx/dsk/bootdg/node@2 487863 5035 434042 2% /global/.devices/node@2
Can I just go on the first name and rename /dev/vx/bootdg/ and /dev/vx/rdsl/bootdg and rename the rootdg_16vol to node@1 or is there a different method.

Yes, you can just rename as a normal veritas volume using vxedit. Make sure you modify the /etc/vfstab file for node1.
1. umount the /global/.devices/node@1
2. renamee
3. modify vfstab
4. mount /global/.devices/node@1
If possible test reboot to verify.
Actually, it doesnot make any difference ifyou leave it that way.

A bad scare: root file system recovery [SOLVED]

Hi, everybody,
The trouble began with an odd message: KDE Daemon: new storage detected (hard disk): open in a new window, ignore. Unfortunately, the hard disk in question is statically mounted via /etc/fstab; should have been mounted all along.
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
none /dev/pts devpts defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 ro,user,noauto,unhide,iocharset=utf8 0 0
/dev/dvd /mnt/dvd udf ro,user,noauto,unhide,iocharset=utf8 0 0
/dev/fd0 /mnt/fd0 vfat user,noauto 0 0
/dev/sdb1 swap swap defaults 0 0
/dev/sdb2 / ext3 defaults 0 1
/dev/sdb3 /home ext3 defaults 0 1
#/dev/sda1 /home/alexey/mnt/a ext3 defaults 0 1
It's /dev/sda1, now commented. Real trouble began when I tried to reboot. The kernel told me there's no root file system on sdb2; it checked the disks unsuccessfully, with scary messages about bad device names and device blocks, advised me to use rootfstype=kernel option, etc. sda1 turned out "bad" too. In fallback mode the system booted, but with file systems mounted read only; not much use... Using some recovery disk I commented out the /dev/sda1 line in /etc/fstab on suspicion that sda is the real offender; tried to reboot, without much success, then rebooted again, and something clicked into place; the system is back to normal, but I fear to approach sda1 . What happened? Any suggestion/link is going to be appreciated. It was pure luck; next time it could be much worse.
Edit:
Looks like 'clicked into place' is just the fallback kernel; kernel-related issue? It ran smoothly after the initial upgrade for a couple of weeks.
Edit:

I had this same damn thing happen. The problem is in the way the kernel gets its info from the bios. The bios has a nasty habit of switching the drives around even when sda is connected to sata1. This became a problem when libata came about and changed all drives to sdxX naming convention.
To fix the no booting problem and the stupid rootfstype= error thing, u need to use Persistent block naming device scheme. Here on the wiki is a page dedicated to this... http://wiki.archlinux.org/index.php/Per … ice_naming
Try it and see if it helps. I used the /dev/by-uuid.

Increase file system size

Hello,
I have solaris9 system where on disk c0t0d0, I have 7 partitions. The first partition shows file system mounted=yes with 10GB space. This file system is near full ( 95% used). I need to increase the size. How can I do that?
I have another partition that shows 30GB and file system mounted=no. Can I create a file system to use this 30 GB? Does it disturb existing file system?
Appreciate your help.

I agree with the guest poster a few posts up. This could be a unique opportunity to think about Bike Trials something that she would really love to do.
Instead of just looking at what's available, think first about what you really want - what would be Bike Trial Seller fulfilling and enjoyable. Is there anything creative she has always wanted to do?
If she loves being a nurse, look at other opportunities within this field that would not involve physical work.
If nursing is just a job, and Bike Store she doesn't enjoy it that much, then look at this as a pointer towards doing something different.
Start making Bike Shop brainstorming lists about all the jobs she would love to and could do - you will come up with something that she can feel excited about.

I ask you details on size, use and contents of following partitions:
/obj1 that is CIFS object cache and /dre1 that is used for the DRE byte level cache
as indicated by you.
In particular I don't understand why if i connect to it through interface web,
from the tab CifsAo->Monitoring->Cache, I see
Maximum cache disk size: 95.75391 GB
Is this value contained in the 121015 MB of /obj1, Right?
Infact I have configured in the Central Manger a Prepositon Directive with Total Size as % of Cache Volume=20
What is the remaining content in /obj1?
While is the redundancy library contained in /dre1
to which WAAS device accesses to compress the traffic to as well as in /plz1?
Please can you do clarify me?
Thanks a lot in advance

Essbase file system

Hi,
We ran out of the existing ESSBASE file system( Analytic Service 9.3.0.1) and we added a new file system on different volume. Now when we open a Analytic Admin. service console and check the properties/disk space tab, we are able to see the name of the new file system but all the values are 0's including total space, free space or used space. We are able to see the old file system values but not the new file system. I have verified that 1 TB space is available on the new file system (via putty session.)
Any idea how we can make it visible on AAS console.
Thanks
AA

Have you extended the current file system or created a new file system mount?
Have you tried starting and stopping Essbase?

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)

Relocating virtual disks to file systems other than dom0:/OVS/running_pool

It looks like the best approach for having multiple large file systems mounted within a domU is by:
1.) Use VM Mgr to create dummy virtual disk (within dom0:/OVS/running_pool/domU)
2.a) if size of dummy is large enough, cp it to a different file system within domU
2.b) if size of dummy is too small, create a new file on different file system within domU using dd
3.) Replace dummy virtual disk file (within dom0:/OVS...) with symbolic link that reference the new replacement file.
Are others doing this? Is there a better way?
Does it cause problems?
is there a way to update VM Mgr to show the correct size if the virt disk is enlarged from the size of the original dummy virtual disk?
Thx...

You can use the /usr/lib/ovs/ovs-makerepo script to add additional repositories under the /OVS mount point. The script takes a block device as a parameter. For example, to create a new shared location on /dev/mapper/mpath1p1, you would run:
# /usr/lib/ovs/ovs-makerepo /dev/mapper/mpath1p1 1 "Shared Storage"
These repositories are then visible to Oracle VM and VM Manager. It will use the repository with the most amount of available space to create your guests for you.

ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

Hi,
i am getting following error, while taking RMAN backup.
ORA-01580: error creating control backup file /backup/snapcf_TST.f
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
DB Version:10.2.0.4.0
while taking datafiles i am not getting any errors , i am using same mount points for both (data&control files)

[oracle@localhost dbs]$ oerr ora 27054
27054, 00000, "NFS file system where the file is created or resides is not mounted with correct options"
// *Cause: The file was on an NFS partition and either reading the mount tab
//          file failed or the partition wass not mounted with the correct
//          mount option.
// *Action: Make sure mount tab file has read access for Oracle user and
//          the NFS partition where the file resides is mounted correctly.
//          For the list of mount options to use refer to your platform
//          specific documentation.
