Red Hat Bugzilla – Bug 4935
Using quotas on some disks causes uninterruptable sleep and crashes.
Last modified: 2008-05-01 11:37:51 EDT
I had quotas running on a 600MB partition for a long time, with no problems. I installed a 17.2GB disk and partitioned it into 4.3GB chunks, and attempted to set up user quotas on the new partitions. When I did so, I encountered these problems: Running repquota to display information on the new partitions causes the repquota process to go into uninterruptable sleep, as reported by ps, and cannot be killed. From that point on, any operation which attempts to write to that new partition hangs into an uninterruptable sleep. When the shutdown procedure attempts to unmount the afflicted partition, it too hangs, and I have to reboot the machine manually, via the reset switch. The hardware is a K6-333, 96MB of RAM, 3.2GB IDE drive (master on primary IDE) and a 17.2GB IDE drive (slave on secondary IDE), CD-ROM (master on secondary IDE). I am currently running without quotas enabled, and everything else works fine. Posts on comp.os.linux.misc brought me into contact with a person from Ohio State University who encountered the same problem. Thanks, Jesse
I have the same problem on HP netserver SMP. linux 6.0, kernel version 2.2.5-15smp extract of dmesg : (scsi0) <Adaptec AIC-7895 Ultra SCSI host adapter> found at PCI 5/0 (scsi0) Wide Channel A, SCSI ID=7, 32/255 SCBs (scsi0) Downloading sequencer code... 374 instructions downloaded (scsi1) <Adaptec AIC-7895 Ultra SCSI host adapter> found at PCI 5/1 (scsi1) Wide Channel B, SCSI ID=7, 32/255 SCBs (scsi1) Downloading sequencer code... 374 instructions downloaded scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.1.15/3.2.4 <Adaptec AIC-7895 Ultra SCSI host adapter> scsi1 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.1.15/3.2.4 <Adaptec AIC-7895 Ultra SCSI host adapter> scsi : 2 hosts.

Me too. For my redhat 6.0 the problem is that when i enable quota on a fs, each operation involving write to a disk will endlessy sleep. I must reset the computer.
I don't know where this bug was hiding, it just got assigned to me. I cannot duplicate any of these behaviours in Red Hat Linux 6.2 or 7.0, our currently supported versions.
