Re: Antw: Re: Q: Slow extraordinarily slow performance of dmraid -s -c -c -c
Hi! I have an update on the ioctl() takes 16 seconds issue: It seems (don't ask me for an explanation) if the buffer size for the SCSI response is too small (in my case less than 18 octets), the wsystemcall to read the SCSI serial number takes 15-16 seconds, while with a buffer of 18 octets or more, it takes 3ms (over an iSCSI-FC-Gateway). Maybe Mike finds this output of a test program useful: === buflen = 17 testprog /dev/sdu 17 SCSI cmd sent: 12 1 80 0 11 0 ioctl duration: 15976 msecs SCSI response: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 resplen = 17, pgcode = 0x 0, pglen = 0 /dev/sdu serial no: : real0m15.979s user0m0.000s sys 0m0.000s === buflen = 18 testprog /dev/sdu 18 SCSI cmd sent: 12 1 80 0 12 0 ioctl duration: 0 msecs SCSI response: 0 80 0 e 50 42 35 41 38 44 34 41 41 55 36 38 33 39 resplen = 18, pgcode = 0x80, pglen = 14 /dev/sdu serial no: PB5A8D4AAU6839 : real0m0.003s user0m0.000s sys 0m0.000s === Regards, Ulrich Ulrich Windl schrieb am 24.09.2012 um 08:57 in Nachricht 50600460.815 : 161 : 60728: Michael Christie micha...@cs.wisc.edu schrieb am 24.09.2012 um 04:46 in Nachricht 1f8fae71-ee7c-4785-a648-24758b18e...@cs.wisc.edu: From what I can tell, it is a dm raid issue or a target issue.

[PATCH v3 3/3] ISCSID: Added iface content override fix
Patch provided by Mike Christie.
This patch fixes the unconditional overwrite of the iface struct
even when the corresponding iface info from the node config was
found and extracted.

[PATCH v3 1/3] ISCSISTART: Saved ibft boot info to the session sysfs
Three new session sysfs parameters are introduced:
boot_root - holds the ibft boot root folder name
boot_nic- holds the ibft boot ethernetN name
boot_target - holds the ibft boot targetN name
This patch copies over the /sys/firmware/boot_root/ethernetN/targetN info
from the boot context to the node_rec.

[PATCH v3 0/3] ISCSITOOLS: Patchset to add the extraction of
Version 3: - Added support for ISCSI_LLD_ROOT support as well - Removed the 'boot_initiator' param because its not useful - Added the 'boot_root' param to hold the 'ibft' or 'iscsi_root'N name to support non-ibft sessions - Moved the boot_nic net param extraction out of the iscsi_sysfs_read_iface routine because it can affect iscsiadm iface config printouts Version 2: - Added boot_initiator to hold the ibft initiator name - Added boot_targetN to hold the corresponding ibft target name - Moved the boot_nic net param extraction to the iscsi_sysfs_read_iface routine - Added extra check before eluding to use the boot_nic info For the case when iscsid is invoked for the first time after pivot root during iSCSI boot, the boot connection would fail to re-connect if the ibft/iscsi_boot sysfs entry contains tagged vlan. The problem was caused by the lack of such info in the iscsi_session sysfs for sync_session to inherit from. The enclosed patchset does the following: 1. Extract and save the ibft-ethernetN name to the boot_context-boot_nic 2. Pass the boot_nic info to be saved to the sessionN sysfs 3. Extract the sessionN boot_nic sysfs info and retrieve the corresponding net params This 'boot_nic' kernel session sysfs entry will only be present for ibft boot. Corresponding kernel drivers will have to add the ISCSI_PARAM_BOOT_NIC attribute to its attr_is_visible table. The last patch provides the fix for the unconditional overwrite of the iface struct even after the ibft net info was already extracted. Please review. Thanks.

[PATCH v3] LIBISCSI: Added new boot entries in the session sysfs
This is the kernel part of the modification to extract the net params
from the ibft sysfs to the iface struct used for the connection
request upon sync_session in the open-iscsi util.
Three new session sysfs params are defined:
boot_root - holds the name of the /sys/firmware/ibft or iscsi_rootN
boot_nic - holds the ethernetN name
boot_target - holds the targetN name

password caching for tgtd
Hi Guys, I spent quite some time trying to figure out why the system was not authenticating, except with a single password that I originally set-up. I had it set to 12345, and that worked. As soon as I changed it, it quit working. I would edit this file, and change the password /etc/iscsi/iscsid.conf node.session.auth.username = username node.session.auth.password = 12345 Then I would edit this file, and change the password to the same thing. /etc/tgt/targets.conf target iqn.2012-11.com.example:backup1 backing-store /dev/sdf1 initiator-address 192.168.8.4 incominguser trenta 12345 /target Then, I found I could have /etc/tgt/targets.conf set to anything I like, and 12345 would still work in /etc/iscsi/iscsid.conf. This all happens even after full restarts. iscsiadm -m node --logout iscsiadm -m node -o delete service tgtd restart service iscsid restart service iscsi restart iscsiadm -m discovery -t sendtargets -p 192.168.8.25 iscsiadm -m node --login Can anyone tell me why this is happening? -- You received this message because you are subscribed to the Google Groups open-iscsi group.

Re: Timeout settings not working?

Advanced Configuration of the readme in /usr/share/docs/iscsi-intiator-utils-$VERSION/REAMDE Believe me, I read that before posting. Ultimately, I just didn't realize that changes to the settings in iscsid.conf would not affect already discovered targets. Ok. I think that is a common mistake, because the tools are odd in that way. I will add some more notes in the README about that.

Re: password caching for tgtd
This was because the tgtd refused to die during a restart. Even a stop did not kill it. So, I had to kill it myself, which resolved the problem.
