Description mwisnicki+freebsd 2013-01-06 20:20:00 UTC

For some reason my SATA drive just disappeared yesterday, maybe due to shitty controller:

ada0 at ata3 bus 0 scbus1 target 0 lun 0
ada0: <WDC WD10EADS-00L5B1 01.01A01> ATA-8 SATA 2.x device
ada0: 150.000MB/s transfers (SATA 1.x, UDMA5, PIO 8192bytes)
ada0: 953869MB (1953525168 512 byte sectors: 16H 63S/T 16383C)
ada0: Previously was known as ad6
atapci0: <Promise PDC20376 SATA150 controller> port 0x1080-0x10bf,0x10c0-0x10cf,0x1000-0x107f mem 0xd0020000-0xd0020fff,0xd0000000-0xd001ffff irq 20 at device 0.0 on pci3
ata3: <ATA channel> at channel 1 on atapci0

so here is the actual problem:

(ada0:ata3:0:0:0): lost device
(pass0:ata3:0:0:0): passdevgonecb: devfs entry is gone
GEOM_ELI: Crypto WRITE request failed (error=6). gpt/ghost_tank2_enc.eli[WRITE(offset=279764992, length=4096)]

/dev: got error 6 while accessing filesystem

I have a crashdump but kgdb is broken.

What is expected outcome of disk removal ?

How-To-Repeat: Just disconnect disk with mounted UFS filesystem.
