Red Hat / Fedora :: Cant Write To Raid - The Permissions Of - Driveid - Could Not Be Determined

Mar 19, 2010

I just did a fresh install of Fedora 11 and added Raid 1 for two additional drives during the install,

So, I have 3 drives. One with the OS, that I boot from. /dev/sdc

Then 2 others in a Raid 1 config, /dev/sda and /dev/sdb -- those are in /dev/md0

Everything with the system is fine. I can boot up, and everything runs great. So then I try to view the Raid and it looks ok when I open 'Computer'. it shows the main OS drive, and what looks like the 2000GB raid drive. So i open it and just see a 'lost+found' folder. Not surprising, b/c I haven't added anything to it. But when I right-click I can't create a folder b/c it's greyed out, I can't drop files in there, and when I get Properties on the drive itself it says 'The permissions of {driveid} could not be determined.'

Ubuntu :: Permissions Could Not Be Determined?

Aug 9, 2010

I am trying to use a second sata 3.5 HD and at other times a USB 2.5 HD. Both prove a pain to use because Ubuntu tells me their permissions can not be be determined. They have only been partitioned to ext2 on Ubuntu. This happens on 9.04 10.04 and 10.10

I have searched the web about this found many answers which just do not work.

Ubuntu :: "This Destination Is Read-Only" / Error Permissions Could Not Be Determined?

Jan 31, 2011

My external hard drive has all of a sudden decided that it wants to be read only, meaning I can not add files to it, delete files, or even move them around. WHen I try to check the permissions, I get the error that permissions could not be determined.

I've tried changing permissions through the terminal using "sudo chmod u+w /media/filessystem", but I only get the message back "chmod: changing permissions of `/media/filesystem: Read-only file system".

I just did a fresh install of Fedora 11 and added Raid 1 following this tutorial:[URL]..

Fedora :: Mounting Windows Server08 From Fedora 8 With Read/write Permissions?

Oct 7, 2009

I have Fedora 8 and we just switched over from a Windows "File Server" to Windows Server 2008 (10.1.1.17). I updated my fstab file and now when I go onto the Windows folders, I can list and read files, even save them, but new files are always read only.

fstab file (some, without the asterisks):
//10.1.1.17/USERS/Jeff/fs /home/mriuser/Desktop/fs cifs rw,username=jsadino,password=**** 0 0

I've tried ntfs-3g, auto, ntfs, smb, some umask combinations, changing ownerships, changing permissions, everything I could think of, but still can't modify new files.

[root@localhost tmp10]# mkdir tmp2
[root@localhost tmp10]# cd tmp2
[root@localhost tmp2]# touch tmp
[root@localhost tmp2]# ls -l

[Code]...

Ubuntu :: Don't Own Any Of Hard Drives - "The Permissions Of "*" Could Not Be Determined"

Jun 23, 2010

I had a problem after an update and ended up re-installing Lucid. Now I don't own any of my hard drives. In the "Permissions" tab of properties they say "The permissions of "*" could not be determined". This is becoming a real problem as my the hard drive that has my Home on it is in "disc failure is imminent" mode and I need to copy everything to another drive urgently.

Red Hat / Fedora :: Format For Server & RAID Setup For Multi Platform Read/write/access?

Jun 23, 2011

I'm looking to set up a server with attached mass storage device and tape autoloader to run linux. It's set up under Windows at the moment. Goal is to have users, connecting from individual workstations and laptops, backup their data to the linux server. On their personal machine, some users run linux, some MacOS, some Windows. I plan to set up the 5 500 GB drives as RAID5. I understand that if setting up as software raid the format is "physical volume for RAID". Under this setup, will Windows users be able to read/write and function as expected? I can't assume only linux user access.

Ubuntu :: Allow Write Permissions To The /var/www Folder?

May 31, 2011

There are lots of tutorials and opinions on file permissions and web hosting.
So lets say I wanted to allow write permissions to the /var/www folder.

which would be best practice?

Chown -R user... allow a specific user to have write capabailities.

use gksudo nautilus (unsure what this does)

or open the folder to all parties.

If anyone has any opinions on file permissions in general or web hosting security then feel free to throw them at me.

Server :: Enforce Write Permissions On Filesystem

Nov 22, 2010

we have a data transfer network drive, shared via nfs and samba.But now I got the special demand to make any of the files read and wirteable, regardsless of the permissions they had before.With acl I get the right permissions (via default values) but the standard unix permissions overwrite this. e.g. when I have 644, it does not care that the group has write permissions)Does someone have an idea (except chmod via cronjob )

General :: Write (Through Or Back) Policy On RAID 1 / 10

Sep 2, 2009

I am trying to prepare my PowerEdge 2950 before CentOS 5.3 installation(web server). I have hardware RAID 1/10 so I will have 2 virtual disks(VD).
First VDRAID 1) - 2 physical disks
Second VDRAID 10) - 4 physical disks
What should be write policy for the VD(RAID 1) and for the VD(RAID 10)? I would have "/var" and maybe "/tmp" on RAID 10.

Server :: Software Raid 5 Write Performance

Nov 16, 2010

I wasn't sure where to post this question so administrators, feel free to move it.I have a media server I set up running Ubuntu 10.4 Server, and I set up a software raid 5 using 5 Western Digital Caviar Green 2TB 7200RPM 64MB drives. Individually they benchmark (using the Ubuntu's mdadm GUI (pali?somthing...) at about 100-120mb/s read write.I set the raid 5 up with a stripe size of 256kb, and then I waited the 20 hours it took to synchronize. My read speeds in raid are up to 480mb/s, but my write max is just under 60mb/s. I knew my write performance would be quite a bit lower than my read, but I was also expecting at least single drive performance. I have seen other people online with better results in software, but have been unable to achieve the results they have gotten.

My bonnie++ results are more or less identical (I used mkfs.ext4 and set the stride and stripe-width).The PC has 2048mb of RAM and a 2.93Ghz Dual Core Pentium (Core 2 Architecture), so I doubt think that's the bottle neck. These drives are on the P55 (P45*) South Bridge SATA controller.

Debian :: Don’t Have Write Permissions To Edit Files

I got Whonix set up, and everything in place to be running correctly and I was on cloud nine. The only problem I'm having is that whenever I try to go in and change my index.html files in /var/www/, or really do anything (add new file/folder, save or delete a file) I get the message that I don't have the right permission to do anything other than open and close the folders and files.

General :: Automatically Set Write Permissions On Mounting A Usb Drive?

Aug 15, 2010

When I mount an external usb drive on linux (CentOs4), the permissions are by default set to read-only. Since there are multiple users on the computer who need to use the external drive, I want everybody to have rw permission for the entire drive. I also want them to be able to mount the drive if the computer has accidentially been shut down. They can use sudo mount to mount the drive, but this will only give them read permission, and I obviously don't want to allow sudo chmod.

Is there a default setting that I can change so that every new external usb disk automatically gets rw permissions?

Ubuntu :: User Doesnt Have Write Permissions To Floppy?

Jan 7, 2010

so i have a limited user (my dad) on Jaunty who has no write access to his floppy disks. Nautilus gives a permission denied error, and i discovered that root owns the floppy drive, thus allowing his read-only. (that write tab on the floppy in on btw). However, when i login as a admin, nautilus says that user has write access. ??? I check the user's user privliges and everything exept "administer the system" is checked. I can copy files on it by logging in as root.

From a Win 7 client, I can copy/create/delete any files on any share on the Ubuntu Samba server so long that is part of my nix file system which is all ext4.This box also has and NTFS partition on it primarily for storage.

Not lloking for a direct answer but if there is anyone else that has issues copying specific types of files to a Samba NTFS partition.

Ubuntu :: Mount CDROM With Read / Write Permissions?

Mar 19, 2010

I am running Karmic x64 on a HP laptop that has a cd/dvd burner. I have a r/w cd with files on it and I wish to add/remove files to it. After it mounts automatically on insertion, I unmount it and remount with:
sudo mount /dev/sr0 -t iso9660 -w /media/cdrom
(I tried assorted other hare-brained things also) but it always says that the filesystem is read only. Do I need to use a different device than sr0? Is it even possible under Ubuntu?

What I want to be able to do, is have create a group, for example called "group1" and set its default permissions to read & write, instead of the usual just read.

So when I add a user into "group1" they automatically have read & write access to all files & directories which is in "group1".

Oh & I use crunchbang 10 (statler) for my desktops & Ubuntu 11.04 for my NFS/print/SSH/etc/etc server

General :: Mounting Ext2 Partition With Write Permissions?

Oct 25, 2009

I need to mount my ext2 partition with write permissions for an average user. Right now, I can only write to the volume using sudo or the root account.

/etc/fstab:

Code:

# Filesystem: Mountpoint: Type: Options: Dump: FSCK:
/dev/sda1 / ext4 defaults 1 1
/dev/sda5 swap swap defaults 0 0

[code]....

can't add the options uid=500,gid=500 to the ext2 volume because it says "bad option" I have 1 question. If you have a volume listed in /etc/fstab, and you try to mount it with different options than the ones listed in fstab, will it mount with the new options, or the fstab options?(e.x. if I try to mount /dev/sda6 with: mount-o auto,user,exec,rw,async. Will it mount with async or sync?)

Debian :: No Write Access To RAID Partition Over Samba?

Aug 9, 2011

I have recently installed Debian on my NAS server. I have also configured Samba for sharing the home directory of a nas user i.e. /home/nas To this directory I have read/write from a windows machine using the nas user credentials. When I mount my RAID partition /dev/md0p1 to the /home/nas directory, I then realize that all content in this directory (files and subfolders) is only owned by the root user. When trying to access from the windows machine the /home/nas directory, I do not have any write access, only read. I have tried both the nas and the root user credentials.

I have also attempted the change the ownership of the mounted RAID partition to the nas user with the -R recursive option, but I get for the internal files/subfolders an error "operation not supported".

How can I overcome this problem? - Is there something not done properly in the /dev/md0 array definition (i.e. ARRAY /dev/md0 level=raid1 num-devices=2 UUID=bddf8b69:c97967b5:cb104784:7fef7cc3 )?- Is there something not done properly in the /dev/md0p1 mounting (i.e. mount /dev/md0p1 /home/nas)?- Should I do any extra configuration before the mounting etc? I would really appreciate any kind of help I could get.

Some background info

b) After OS boot, when I do a:
# cat /proc/mdstat,
I get:
Personalities : [raid1]
md0 : active (auto-read-only) raid1 sda1[0] sdb1[1]
4200896 blocks
unused devices: <none>

Ubuntu Servers :: WRITE Performance Down On RAID 1 Array

Sep 7, 2010

I'm currently experiencing some serious issues with WRITE performance on a RAID-1 array. I'm running Ubuntu 10.04 64 bit server with the latest updates. To evaluate the performance ran the following test: [URL]... (great article btw!) Using dd to measure, write performance is only at 8.7 MB/s. Read is great though at 74.5 MB/s. The tests were ran straight after rebooting and I have not (YET!) done any kernel tuning or customization, running the default server package of the Ubuntu kernel. Here's the motherboard in the server: [URL]... with a beta bios to support drives over 300GB.

[code]...

As you can see from the bo column there is definitely something stalling. As per top output, the %wa (waiting for i/o) is always around %75 however as per above, writes are stalling. CPU is basically idle all the time. Hard drives are quite new and smartctl (smartmontools) does not detect any faults.
