I have been testing RAID recov= ery and have noticed that I get timeouts when rebuilding the array (but not= if I just read /dev/ar0 normally). Here's part of dmesg.. =2E.. atapci0: <Promise PDC20771 SATA300 controller> port 0xa400-0xa47f,0xa000-0x= a0ff mem 0xfab00000-0xfab00fff,0xfaa00000-0xfaa1ffff irq 16 at device 11.0 = on pci0 ata2: <ATA channel 0> on atapci0 ata3: <ATA channel 1> on atapci0 ata4: <ATA channel 2> on atapci0 =2E.. ad4: 305245MB <WDC WD3200SD-01KNB0 08.05J08> at ata2-master SATA150 ad6: 305245MB <WDC WD3200SD-01KNB0 08.05J08> at ata3-master SATA150 ar0: 305175MB <Promise Fasttrak RAID1> status: READY ar0: disk0 READY (master) using ad6 at ata3-master ar0: disk1 READY (mirror) using ad4 at ata2-master =2E..

I have tried 4 sets of SATA cables with no change in behaviour. I have also seen the array 'split' where the code sees 2 arrays (one on each disk) when I plug the drive back in. I would have expected the ATA code to= =20 notice it had the same ID number (I am assuming that when the array is crea= ted it gets a moderately unique ID) but the new disk has an older generation number and so not add it. =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart12428980.a2kdz4Qfjm Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (FreeBSD) iD8DBQBE5Bso5ZPcIHs/zowRAqWgAJ9SwNpTvJeij1VhXPSjVrxVtX4wWwCePTL8 LXPL/Y1lfdQ9v8HI3IacznA= =MLh/ -----END PGP SIGNATURE----- --nextPart12428980.a2kdz4Qfjm--
