"Serious" means: just now Problems caused by storage hardware. Joseph Salisbury (jsalisbury) wrote on 2015-03-02: #14 Would it be possible for you to test the latest upstream kernel? However immediately thereafter (git linux-stable) I got random contents.

The exact cause of this issue is still under investigation in private bugzillas, but the cause in remote storage situations appears to be hardware/firmware related in a majority of the cases. Months of run time with no issues so far, the array enclosure and the server itself are on a UPS.

My OCZ Vertex 3 is running more than 1 year now. 0 problems. Bad SSD's. Fix?

But my files get corrupted after 15-20 days. This is 16 2 TB volumes in RAID6 -- Am I just screwed by the volume size? [ 462.680976] EXT4-fs error (device md8): ext4_mb_generate_buddy:739: group 30561, 15353 clusters in bitmap, 0 I have even tried deleting a 1.4 GB file from the filesystem and copying it back.

SMART only captures ~2/3 of drive failure modes, so things like AC ripple noise in your power supply can cause drive problems that SMART doesn't capture. Rebuild the FS from scratch and see if ext4 corruption continues. 2. Thanks in advance.

Going back to the Kernel release 3.0.0-19 of Ubuntu 11.10 makes the problems going away. It's still present in Linus' tree as of a9e1e53bcfb29b3b503a5e75ce498d9a64f32c1e (10-Apr).

See full activity log To post a comment you must log in. Ugh, yea it is a bit old, but it's 12.04.5 LTS which is supported until 2017. My server configuration: 1 x SATA HDD for the OS 4 x 2TB SATA HDD (device md0): RAID 5 on EXT4 Possible sources of the errors: I (or the system automatically) It would seem that using the exact same OS/kernel/binaries, the error doesn't happen on a fresh filesystem, I guess there must have been something about the filesystem image itself that triggered

The ureadahead segfault seems to be NFS related, as NFSD started immediately prior to that. Clean the hardware with compressed air and reseat all of the cabling. Thanks in advance. We doesn't seems to have this problem on others nodes runnning: Intel(R) Xeon(R) CPU E5345 @ 2.33GHz Intel(R) Xeon(R) CPU 5160 @ 3.00GHz Intel(R) Xeon(R) CPU E5320 @ 1.86GHz Intel(R) Xeon(R)

But it crashed again next day :( Seems to be related to memory usage at least for last crash. How do computers remember where they store things? I moved all of the disks to a different (identical model) enclosure and it's rebuilding now at 15536K/sec. Perhaps the journal is out of space and it isn't a file system issue?

Why is it a bad idea for management to have constant access to every employee's inbox Why is absolute zero unattainable? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . The fact that it hasn't happened on other VMs leads me to believe the bug is inside the guest rather than with KVM - perhaps ext4 or the virtual disk driver.

I wonder if SSDs can be used with kernel 3.2 and above?

It was crashing consistently with -m 512 about a minute into the synthetic FS load.

yes Free inodes count wrong for group #0 (0, counted=11). After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" to try again to boot into default mode.
