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.'
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.
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 don't know exactly whats wrong, it won't play DVD's or recognize that a DVD is in it. I checked in terminal with sudo lshw -c disk, it shows the correct info for the drive but still says status:nodisk.Double clicking or right click>open doesn't do anything either. Is there something I'm missing? Whats weird is audio CDs are recognized and will play just fine.(checked with multiple DVDs
I just did a fresh install of Fedora 11 and added Raid 1 following this tutorial:[URL].. Now I see the filesystem when I open 'Computer' in the GUI, and I open it and see 'lost+found', but i can't write to the drive. The option is simply greyed out. And when I view Properties on the drive and go to Permissions, it says 'The permissions of {driveid} could not be determined.'

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
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.
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.
i have sevrel hard drives among 3 pcs all (root of the drive)re shared (except os drive)one pc i use for captureing tv this drive has no write permission from my local pc but all other hard drives have read/write permissions
I am trying to change the write permissions on a file and On the screenshot you will see where i have underlined, its states i dont have owner rights to modify this file, how do I get owner Permissions when this is my installation..
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 )
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.
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.
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.
I have created directories in root. I am looking for the chmod command to allow all users read and write permissions to a specific directory. I have done chmod 775 for a file but I need this for a directory. This includes permissions on all files and sub directories.
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?
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. I can copy/create/delete anything on this partition form the same Win 7 client with the exception of Quickbook save files.I have scoured the web looking for anything close to this but have yet to find anything that looks similar. 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.
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?
I'm pretty new to Linux but I know my way around. I've gotten Google Earth downloaded and am trying to install it. Everything is fine until I try to install it into /usr/local (or somewhere in there). The Google Earth Setup keeps telling me that I do not have write permissions on this directory. Question: How do I change the write permissions for this folder? Or should I install the program somewhere else? The last program I installed (xMind) installed into /usr/local.I am the only user (administrator
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
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.
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?)
i am using SUSE 11.0 KDE 4.0 i had root account installed in 8.0 Gb drive, and a normal account installed in 4.0 Gb drive .And i was using rest of space for windows (NTFS). Now i want to use a drive (NTFS) to linux for additional requirements. i want get write permissions to that drive .. am i able to get ??r else ..i need to format with EXT3?
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>
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.

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.
