Hello all! I am using an Asus EEE Box with Fedora 9 as a NAS. I have found a way to spin-down my USB harddisks with the sg3 utils, but the system occasionally times out on write actions to the disk. I usually access the disk through SMB of NFS, which forces the disk to spin up first. Sometimes the system opens the disk by itself, throwing an error. lost page write due to I/O error on sdf1 Is there any way to increase the system timeout when accessing/writing-to the drive? Or should I go ask the ext3 people? Or does sg_start not notify the kernel the device has been stopped?
In response to the sg_start question, it does not notify the kernel that the device has been stopped. IMO stopping a disk containing a mounted file system is asking for trouble, however I don't think that it the role of such low level utilities to detect and prevent such things. As for informing the kernel, if I discovered a way to do that, then I would need to investigate how that might be done on other OSes that sg3_utils is ported to (e.g. Windows). So I would prefer not to go down that path. Doug Gilbert
When the system fails, I get the following error: Nov 4 23:50:42 EEE-Box kernel: sd 6:0:0:0: [sdf] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_OK Nov 4 23:50:42 EEE-Box kernel: end_request: I/O error, dev sdf, sector 976767873 Nov 4 23:50:42 EEE-Box kernel: Buffer I/O error on device sdf1, logical block 122095984 Nov 4 23:50:42 EEE-Box kernel: sd 6:0:0:0: [sdf] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_OK Nov 4 23:50:42 EEE-Box kernel: end_request: I/O error, dev sdf, sector 976767873 Nov 4 23:50:42 EEE-Box kernel: Buffer I/O error on device sdf1, logical block 122095984 Nov 4 23:50:52 EEE-Box kernel: sd 6:0:0:0: [sdf] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_OK Nov 4 23:50:52 EEE-Box kernel: end_request: I/O error, dev sdf, sector 4361 Nov 4 23:50:52 EEE-Box kernel: Buffer I/O error on device sdf1, logical block 545 Nov 4 23:50:52 EEE-Box kernel: EXT3-fs error (device sdf1): ext3_readdir: directory #2 contains a hole at offset 0 Nov 4 23:50:52 EEE-Box kernel: sd 6:0:0:0: [sdf] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_OK Nov 4 23:50:52 EEE-Box kernel: end_request: I/O error, dev sdf, sector 1 Nov 4 23:50:52 EEE-Box kernel: Buffer I/O error on device sdf1, logical block 0 Nov 4 23:50:52 EEE-Box kernel: lost page write due to I/O error on sdf1 Nov 4 23:50:52 EEE-Box kernel: sd 6:0:0:0: [sdf] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_OK Nov 4 23:50:52 EEE-Box kernel: end_request: I/O error, dev sdf, sector 265 Nov 4 23:50:52 EEE-Box kernel: EXT3-fs error (device sdf1): ext3_get_inode_loc: unable to read inode block - inode=2, block=33 Nov 4 23:50:52 EEE-Box kernel: ------------[ cut here ]------------ Nov 4 23:50:52 EEE-Box kernel: WARNING: at fs/buffer.c:1183 mark_buffer_dirty+0x23/0x6a() (Not tainted) Nov 4 23:50:52 EEE-Box kernel: Modules linked in: joydev cpufreq_stats xt_tcpudp iptable_filter ip_tables x_tables nfsd lockd nfs_acl auth_rpcgss exportfs bridge bnep rfcomm l2cap bluetooth fuse sunrpc ipv6 loop dm_multipath snd_hda_intel snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device video snd_pcm_oss output snd_mixer_oss snd_pcm i915 snd_timer button snd_page_alloc drm snd_hwdep snd i2c_algo_bit i2c_i801 r8169 pcspkr i2c_core soundcore serio_raw iTCO_wdt iTCO_vendor_support usb_storage sg dm_snapshot dm_zero dm_mirror dm_mod ata_piix pata_acpi ata_generic libata sd_mod scsi_mod ext3 jbd mbcache uhci_hcd ohci_hcd ehci_hcd [last unloaded: microcode] Nov 4 23:50:52 EEE-Box kernel: Pid: 1760, comm: ls Not tainted 2.6.25-14.fc9.i686 #1 Nov 4 23:50:52 EEE-Box kernel: [<c0427911>] warn_on_slowpath+0x47/0x73 Nov 4 23:50:52 EEE-Box kernel: [<c062d850>] ?
