stdin corrupted crc32 mismatch
-
I’m still getting this error, but it’s inconsistent. It only happens sometimes… sometimes an image job will work perfectly, other times I get this CRC32 error. I’m using my standard SOE not the one I originally linked in this forum post. It just has normal 100Mb system reserved, then the rest is on one partition.
Its almost like an error from the partclone transfer?
-
Doesn’t CRC check for broken sectors? Is it possible the target HDD has a couple of broken sectors?
-
@Quazz It happens randomly though. It’s the same image being deployed every time, yet we randomly get these CRC errors. I think it’s maybe a glitch with partclone.
-
@andyroo54 when I was having the random crc issues it was related to my servers storage setup getting corrupt. I was using a glusterfs setup with was always problematic at best within my environment. In fact, it was the reason I added the --ignore_crc flag. In most cases the crc issue was fixed after adding the flag but if the data was corrupted enough I’d get partclone all the way to 100% then the same errors you’re seeing.
What is output on the server when this happens from the command
dmesg? -
@Tom-Elliott I just got another CRC32 this is the output Tom:[img]http://i.imgur.com/L2RtsT2.png[/img]

@andyroo54 What is your server disk where you have /images stored on? Maybe try
dmesg | grep sda(if /dev/sda is your disk…) -
@Sebastian-Roth It’s on a RAID 5 storage of sandisk SSD’s in a HP DL380 server.Do you think the SSD’s might be causing an issue?
-
@andyroo54 From the output you posted I am not sure if sda really is your system disk… Maybe show us the output of
lsblk…Soft RAID or real hardware RAID controller??

It’s hardware RAID in a HP DL380 server running esxi 5.5
-
@andyroo54 I’m assuming it’s formatted as either ext3 or ext 4. Maybe run a full blown fsck on it?
-
@Tom-Elliott I booted into the live CD and ran this and this is the output. Not sure if I’m doing it right

I ran gparted instead.

FYI, after using gparted, I was able to deploy the image without a CRC32 error. I’ll do some more testing to be sure! Thanks guys

@andyroo54 Are you able to deploy do a differnent machine/disk?? Possibly the destination disk is the problem??
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

@Sebastian-Roth I don’t think it was destination disk. I think the raid has some corruption. But we wouldn’t have seen it directly as it was mounted as an individual disk. When he went into gparted, it found the corruptions and was able to take a course of action.
-
Whoops, sorry. Didn’t properly read the @andyroo54’s last post… Good to hear that you solved it!
-
Have to mark this as unsolved because it’s still happening…!
Its so odd… you deploy and get the CRC32 error, then if you deploy it again, the next time it works…? It’s random. Surely if the disk was corrupted, then it would consistently NOT work, not randomly work and randomly not work.
-
@andyroo54 Random issue like this sounds like a memory problem to me (just a wild guess)… memtest?
-
Pass complete, no errors…
-
@andyroo54 I don’t think it would matter. This especially considering it works, then it doesn’t. I suspect the client machines memory be the issue and/or the disk is about to fail? Does the SMART report anything on the server?
