HA takeover disabled by &#39;unsynchronized log&#39; messages is the nastiest failure mode: the pair looks healthy until failover does nothing. Check log sync after every upgrade. https://netapp-blackbox.pages.dev/news/?utm_source=mastodon&amp;utm_medium=social&amp;utm_campaign=w4&amp;utm_content=photo

NTAP +3.92% to $223.93 today, +11.3% in a month. Boring storage hardware, beating the software story. A pop is not a thesis. When did you last replace a controller pair because of a share price?

9.17.1P10 will panic a node on a scheduled SnapMirror update: sk_msg_proc.c:853, assertion failure. CONTAP-799345. No workaround and no corrected patch level published yet. The reboot is the loud part. The transfer that stopped is the one that costs you RPO. Which do you check first?

NTAP is up 12% in a month into the print. The line to watch is not revenue. It is units vs price. https://netapp-blackbox.pages.dev/news/2026-10-27-earnings-preview-what-to-expect-from-netapp-s-/?utm_source=mastodon&amp;utm_medium=social&amp;utm_campaign=w4&amp;utm_content=news-earnings-preview

NTAP +11.3% in a month into earnings. All-flash share, margins, guidance now have to defend the price. $227.58, +2.48%. https://netapp-blackbox.pages.dev/news/2026-10-27-earnings-preview-what-to-expect-from-netapp-s-/?utm_source=mastodon&amp;utm_medium=social&amp;utm_campaign=w4&amp;utm_content=ntap-earnings

FSx for ONTAP now has AI-optimised storage options. A training read that crosses the S3 boundary costs more than the capacity it saves. Which constraint hits you first, throughput or capacity?

Arrow is now reselling NetApp Keystone as a managed service. The fine print that matters: billing moves to the partner, but QoS policy, SnapMirror lag and capacity headroom stay in your pager rotation. Consumption pricing never removed the on-call.

Arrow is the first distributor selling managed Keystone. No price, no SLA. https://netapp-blackbox.pages.dev/news/2026-10-29-arrow-electronics-introduces-managed-storage-s/?utm_source=mastodon&amp;utm_medium=social&amp;utm_campaign=w4&amp;utm_content=arrow-keystone-managed

Takeover refused: one transient disk error on FSx for NetApp ONTAP and the partner disks are gone (CONTAP-697033). Check partner disk inventory before the handover. https://netapp-blackbox.pages.dev/news/week/?utm_source=mastodon&amp;utm_medium=social&amp;utm_campaign=w4&amp;utm_content=contap-697033

volume move show: hard cutover deferred, six hours. Replication at 100%. The copy is done; the swap is not. Something is holding the cutover window shut. First check: destination free space, open client handles, or the SnapMirror policy?

NetApp KB: ARP/AI may not catch ransomware that uses certain file extensions. Detection tuned to file types has blind spots - test it against what your workloads actually write. https://netapp-blackbox.pages.dev/security/?utm_source=mastodon&amp;utm_medium=social&amp;utm_campaign=w4&amp;utm_content=arpai
