Hi all, I have an older P4 running FreeBSD 7.0 which I use as a web/file server, WAP, and ADSL gateway. The OS and /usr partition are on 30 GB Seagate Barracuda IDE drive, ad0.
In addition, I have added two 500 GB IDE drives which I scavenged from a pair of La Cie external USB enclosures. The one is a Hitachi, ad2, and the other a Maxtor, ad3. I use this for storing a large collection of MP3s and for backing up the home partitions of several Linux clients on my network. I customarily share ad2 via NFS with my Linux clients. Here is where my problem begins: After mounting the NFS share, the Linux client eventually (24-48 hours) runs into to trouble; the share is no longer visible, and this tends to wreak havoc with Gnome. Looking in dmesg on the client, I see this: nfs: server venus not responding, timed out Looking in /var/log/messages on the FreeBSD server, I see the following (here is a week's worth): Jan 8 03:01:10 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 8 03:06:06 venus kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 9 03:01:09 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 9 03:06:13 venus kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 10 03:01:10 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=70508479 Jan 10 03:06:07 venus kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 10 04:02:35 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 10 19:26:07 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=49302399 Jan 11 03:01:10 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=58711199 Jan 11 03:06:14 venus kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 11 04:02:27 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 12 03:01:10 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 12 03:06:13 venus kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 13 03:01:10 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=12159 Jan 13 03:06:14 venus kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 14 03:01:10 venus kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Jan 14 03:06:14 venus kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=287 Any ideas on what is going on here? Note that only the two 500 GB data drives cause these errors; there is never a complaint about the 30 GB system drive. The two data drives are still online, and there is no problem accessing them through the server; it is just NFS which can't handle it. FWIW, I've tried using 'soft' as an option in the NFS fstab entry on the clients to no avail Thanks for any suggestions. ----- Colin Brace Amsterdam http://lim.nl -- View this message in context: http://www.nabble.com/kernel-errors%3A-TIMEOUT---READ_DMA-tp21455082p21455082.html Sent from the freebsd-questions mailing list archive at Nabble.com. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
