Hello, I got help, and found the solution.
The user direct was incorrect (on z/VM level). This line: IPL SUSE11DB PARM DASD=300-3FF The correct line: IPL SUSE11DB PARM DASD=300-5FF The DASD range was not extended. This is working now! About the root cause: Before the extension of LVM and creating of the new LV and FS, the chccwdev was enough. But after and during the first boot, the lvm was not able to find the necessary PV and building up the LV and FS, so the filesystems was harmed or missed. But I got another idea also: use dasd_configure to configure the new dasds: Example: dasd_configure 0.0.0400 1 0 dasd_configure 0.0.0401 1 0 dasd_configure 0.0.0402 1 0 ... This command should bring the dasd online and create a udev rule to make it persistent at ipl time. As I see now, this second solution would be good also (it was not tested, because of the server is very sensitive and in production). About the affected system: myhostname:~ # cat /etc/SuSE-release SUSE Linux Enterprise Server 11 (s390x) VERSION = 11 PATCHLEVEL = 4 myhostname:~ # Kind Regards : Csaba Polgar From: Mark Post <mp...@suse.com> To: LINUX-390@VM.MARIST.EDU Date: 2018.01.29 19:49 Subject: Re: Buffer I/O error on device dm-28 Sent by: Linux on 390 Port <LINUX-390@VM.MARIST.EDU> >>> On 1/28/2018 at 09:51 PM, Csaba Polgar <csaba_pol...@hu.ibm.com> wrote: > Hello, > > I'm newbie on this forum, but I would like to ask your help.

Or what is missing > from the configuration? There's not nearly enough information to know what's going on, yet. First, what distribution is this? What maintenance level? Next, is this an LVM setup, or something else? If LVM, then some output from things like "vgs" "pvs" "vgdisplay -v" and so on would be helpful.
