Hello, I'm newbie on this forum, but I would like to ask your help. (Sorry, if I brake any protocol/usage guideline.) Could someone please help to solve the below issue?
We have created a big filesystems (with 2 TB) 1 and half month ago. And there was no error message or any complain from the customer. After a new boot, I got the below error message: Jan 28 20:16:50 myhostname kernel: Buffer I/O error on device dm-28, logical block 536870896 Jan 28 20:16:50 myhostname last message repeated 2 times Jan 28 20:17:07 myhostname kernel: Buffer I/O error on device dm-28, logical block 536870896 Jan 28 20:17:12 myhostname last message repeated 6 times from dmesg: ...

Most of dasd were online, but I saw more offline dasd: myhostname:~ # lsdasd -a Bus-ID Status Name Device Type BlkSz Size Blocks ============================================================================== 0.0.0400 offline 0.0.0401 offline 0.0.0402 offline 0.0.0403 offline 0.0.0404 offline 0.0.0405 offline 0.0.0406 offline 0.0.0407 offline ... How can it be online (active) before the Linux boot? Or what is missing from the configuration?
