*********************** This mail has been scanned by InterScan MSS. ***********-*********** I just found out what triggled the Apparent buffer overflow! When there are a lot of drbd devices and some of them are doing syncing. Apparent buffer overflow msg will show up in dmesg if I execute "/etc/drbd status" command. and it also usually crash the kernel (see attachment file: drbd.log2) David Huang -----Original Message----- From: David Huang [mailto:david_huang at proware.com.tw] Sent: Tuesday, August 16, 2005 12:35 PM To: drbd-user at lists.linbit.com Subject: Apparent buffer overflow Hello everyone I am running DRBD 0.7.11 on kernel 2.6 with LVM2 and XFS filesystem. I treid to create and bring up the DRBD devices one by one. Everytime when I reached to number 30 or 31, kernel became unstable and crashed after a few seconds (kernel panic) . I dmesg before it crashed ( see the attachment file). There are a lot of "proc_file_read: Apparent buffer overflow!" msg. Is it the limitation of DRBD? or is it just a bug? cheers David -------------- next part -------------- A non-text attachment was scrubbed...
