Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: If I use cp -a, or cpio -i, or cpio -p to copy a reasonably large number of files (say, > 100M) onto an ext3 filesystem on my ultra ATA/100 disk drive controlled with a Promise Ultra 100 TX2 controller (pdc20268) the file system (or perhaps the driver, not sure which) hangs up the copy process. All subsequent processes attempting to access that file system or another one under the same controller but possibly a different ide channel will also hang. These processes cannot be killed. It is impossible to reboot except by reseting the machine with the big red button, or sometimes with ctl-alt-del *after* entering halt -nfip which itself does not do the job (it also hangs). Can copy huge files onto the same file system (eg: 3+ GB) with no problem, so I don't think its a hardware problem. workaround1: easy, use ext2 (no journaling). workaround2: the same cp -a, etc. work fine on my older udma2 IBM drives, controlled by the on-motherboard IDE controller. This is an SMP (dual) supermicro P6DBU. There is also a SCSI controller and drives, but these don't have the same problem - a different problem - but that's another story. 1GB ECC DRAM. Disks are Western Digital WD1000BB (100GB). File system covers entire disk and is around 95MB in size but was either empty or had a few large files on it. kernel: 2.4.18-19.8.0 (stock redhat 8.0 + up2date) Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. mkfs -t ext3 /dev/hdg5 on a largish IDE disk (WD caviar) controlled by pdc20268. This may need to be a biggish (90+GB file system) 2. mount /dev/hdg5 /mnt/bigdisk 3. cp -ax / /mnt/bigdisk/root Actual Results: The cp -ax hangs (stops copying) and all subsequent commands that access any filesystem on a disk controlled by the pdc20268 also hang. They cannot be killed. reboot difficult but necessary. Expected Results: uh, duh, the cp -ax should have copied the whole root filesystem. Additional info: workaround1: easy, use ext2 (no journaling). workaround2: the same cp -a, etc. work fine on my older udma2 IBM drives, controlled by the on-motherboard IDE controller.
