Rhel5 read only file system

Have you replaced the failed disk from the mirror raid array? It may take some time to rebuild it. What is true in the failure for some FS's become read-only can be the kernel version? And fix it in the 2. Comments 5. Dear Team , One of server Prod server went into read only mode , All file systems are hosted on internal disk.

Let me know if anything else is needed [root dcsametime01 notesdata] dmidecode dmidecode 2. Table at 0x7F6BD Newbie 7 points. The file system is configured to be mounted as read-only by default. But these file systems can be also mounted as read and write. The rw option can be used to mount read and write. Save my name, email, and website in this browser for the next time I comment.

While trying to restart apache2 web server you may get this error like below. If a filesystem has been mounted read-only, chmod will not work since it's a write operation too.

If the device has a write lock on it like SD memory cards , you need to turn it off. Hardware locks cannot be disabled by software. Note that the write lock on SD memory cards is located from the sight you see the letters near the up left corner and it looks like a very small switch.

Some filesystem drivers may also not support write operations, this is the case with the older NTFS module supported by Linux. For NTFS filesystems, be sure to use the ntfs-3g driver which should be picked automatically nowadays. If not, you can force the driver with something like:. For NTFS file systems this problem may occur when it is not properly unmounted probably by unexpected shutdown of windows. In such cases the file systems are marked as locked.

I had this problem occur on several USB sticks. Each time I searched for an answer and tried various suggestions, including using Terminal to run commands, reformatting on both Linux and Windows machines, etc. All to no avail. It happened to me again today so again I went looking to see if I could find a solution. I tried the things here, but they didn't work.

Out of desperation I again went to Disk Utility. I unmounted the drive and then hit "Format" on the partition portion, not the drive portion - USB only had the single partition. Then I went to the drive portion and again reformatted the single partition as a master boot drive and monkeyed a bit more with it.

If the USB stick is mounted as read-only. Go to Disk Utility and unmount the disk. Then click on Check Filesystem if there are no problems remount the disk. After mounting the disk it should work correctly, at least that is how I solved this problem. I couldn't easily take my problematic NTFS-formatted external drive back to the Windows system that had apparently failed to dismount it safely causing Mint to insist on mounting it "read-only". But the easy answer for me was to run the Mint "Disks" utility and select "Repair filesystem" Target Release :.
