(The large I/O problem persists in that release.) This patch adds the new identifier to the 1024 sector blacklist, the old one having been added in commit 9055082fb100cc66e20c048251d05159f5f2cfba "scsi: add Synology to 1024 sector blacklist".

Could be worth it. As far as I can see, they manufacture no directly attached drives (only NAS devices, which I presume are all affected by the same problem as mine). -- Michel Meyers ^ permalink raw reply [flat|nested] 8+ messages in thread

SYNOLOGY have released a new version of their OS indicating that they have worked to fix the iSCSI problem (and another one to actually make that update installable): https://www.synology.com/en-global/releaseNote/RS10613xs+ - "Fixed multiple issues that might cause iSCSI service to hang under heavy loading and performing Vmware VAAI commands." - "Fixed an issue where DSM 6.0-7321 Update 1 could not be normally installed with Auto-Update." (They have not updated my support ticket on this case thus far.) Both my SYNOLOGY appliances now seem to show correct vpd data when queried: root@server:/# sg_vpd -p bl /dev/sdb Block limits VPD page (SBC): Write same non-zero (WSNZ): 1 Maximum compare and write length: 1 blocks Optimal transfer length granularity: 128 blocks Maximum transfer length: 8192 blocks Optimal transfer length: 1152 blocks Maximum prefetch length: 0 blocks root@server:/# sg_vpd -p bl /dev/sdd Block limits VPD page (SBC): Write same non-zero (WSNZ): 1 Maximum compare and write length: 1 blocks Optimal transfer length granularity: 128 blocks Maximum transfer length: 8192 blocks Optimal transfer length: 512 blocks Maximum prefetch length: 0 blocks I am currently running tests with an unmodified Debian 4.4.0-1-amd64 kernel, so unless I can reproduce the problem, I suggest we leave the current blacklist as is (thereby only quirking the pre-6.0 SYNOLOGY volumes that are affected) and discard the new patch. -- Michel ^ permalink raw reply [flat|nested] 8+ messages in thread
