https://bugzilla.novell.com/show_bug.cgi?id=714512 https://bugzilla.novell.com/show_bug.cgi?id=714512#c0 Summary: Filesystem goes read-only in VMware Classification: openSUSE Product: openSUSE 11.4 Version: Factory Platform: VMWare OS/Version: openSUSE 11.4 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: mmunoz.ademn@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/13.0.782.215 Safari/535.1 I've an issue with a opensuse 11.4 guest VM. The root partition goes read-only while the VM was running normally. I can't write data to disk, I need reboot. The log (/var/log/messages) show this: Aug 22 10:57:02 guest1 kernel: [508161.475307] mptscsih: ioc0: attempting task abort!

The mount, uname, an SuSE-Release commands and text shows these output: guest1:~ # mount devtmpfs on /dev type devtmpfs (rw,relatime,size=244048k,nr_inodes=61012,mode=755) tmpfs on /dev/shm type tmpfs (rw,relatime) devpts on /dev/pts type devpts (rw,relatime,gid=5,mode=620,ptmxmode=000) /dev/sda2 on / type ext4 (ro,relatime,user_xattr,acl,barrier=1,data=ordered) proc on /proc type proc (rw,relatime) sysfs on /sys type sysfs (rw,relatime) debugfs on /sys/kernel/debug type debugfs (rw,relatime) securityfs on /sys/kernel/security type securityfs (rw,relatime) none on /proc/fs/vmblock/mountPoint type vmblock (rw,relatime) guest1 # uname -a Linux guest1 2.6.37.6-0.5-desktop #1 SMP PREEMPT 2011-04-25 21:48:33 +0200 i686 i686 i386 GNU/Linux # cat /etc/SuSE-release openSUSE 11.4 (i586) VERSION = 11.4 CODENAME = Celadon I read this Novell document 7005154 with a SLES fix, but they doesn't have an opensuse 11.4 fix: http://www.novell.com/support/search.do?cmd=displayKC&docType=kc&externalId=7005154&sliceId=1&docTypeID=DT_TID_1_1&dialogID=124918554&stateId=0 0 258916088 This another vmware link is related too: http://kb.vmware.com/selfservice/dynamickcInt.do;jsessionid=ADE81C639B90B59BBA491CEE21DF4C64?micrositeID=&cmd=show&docType=kc&sliceId=2&forward=nonthreadedKC&externalId=51306&stateId=0%200%208616976 vmware KB I'm using "VMware Server Version 2.0.2 Build 203138" over Win 2k3 64bit like host. In this blog, a computer student has published a patch for kernel 2.6.39, but I'm using the 2.6.37.6-0.5-desktop version, and I prefer a released fix of opensuse: http://weltall.heliohost.org/wordpress/2011/05/14/running-vmware-workstation... RedHat Enterprise, SUSE Enterprise and Ubuntu have a fix, and I'm using a fresh linux kernel. At this moment, exists a fix for opensuse 11.4? Regards, Marcelo Reproducible: Couldn't Reproduce Steps to Reproduce: 1. 2. 3. Expected Results: let the root partition in normal mode, i.e. the filesystem read-write mode. I need reboot the server in order to reestablish the normal service. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The vmware article doesn't talk about a patch vmware, they say "This Linux kernel bug has been fixed in different updates of different Linux distributions. Not all kernel versions include the patch. Contact your Linux Distributor for more information."
This is from Comment #0: | In this blog, a computer student has published a patch for kernel 2.6.39, but | I'm using the 2.6.37.6-0.5-desktop version, and I prefer a released fix of | opensuse: | http://weltall.heliohost.org/wordpress/2011/05/14/running-vmware-workstation... That blog entry currently has a vmware patch for 2.6.39. The other links supplied in Comment #0 point to patches that already exist in openSUSE 11.4.
The underlying O/S didn't had problems when the Guest-VM filesystem got in read-only mode, and the others guest-vm on the same server were running normally, included an Opensuse 11.3 VM
The underlying OS is supplying storage to the VM. If a request to that storage takes a little too long (as defined by the Guest OS), then the filesystem can get an error, in which case it remounts that filesystem as read-only. That does not mean the Host OS would notice any problem. Have you tried my request from Comment #7? In the mean time, I will try loading openSUSE 11.4 as a Guest VM on my OS X host, but I do not have any windows host with RAID to duplicate your configuration. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'm using VMware Server Version 2.0.2 Build 203138
I can't reproduce the issue. It happened once, and then I had to restart the VM
That is consistent with a transient I/O error, whether logged or not in the underlying OS. If it does happen again, please try the remount test requested. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
